Excel: How to Best Import External Data into Excel & Import data from the Web to Excel
 
11:16
Get the full course: http://www.xelplus.com/onlineAdvancedExcelCourse Excel has various tools that can help you easily clean up your raw data for further analysis. Apart from using formulas and formatting, there are two useful Excel features that let you easily clean up. One method is text to columns feature and the other to import external data. The Get External Data tool can be used to import and analyse data from other systems. This tool is also useful for importing data to run your dashboards or do further analysis using pivot tables, etc. Usually you can get data extracts from any system (e.g. “.dat” or “.csv” from Oracle, “.xml” files from SAP, etc.). These can be imported into Excel. Importing External Data also gives you control over the decimals and thousand separator, especially if you’re dealing with international companies. In the US, the decimal is dot and the comma is a thousand separator and in most European countries it’s the other way round, where the comma is a decimal and the dot a thousand separator. It’s always safest to Import it properly with the Excel Data Import wizard! After importing press Ctrl + T to create a table out of it. You can create a pivot table off this one, and when you do, even if you add more data to it, the pivot reflects the new data. Importing Data from the Web / Internet into Excel – creating web queries that refresh automatically: In Excel you can also import data directly from the web. You basically create a web query which you set to refresh automatically based on your preference. ➹ ➹ ➹ My Online Excel Courses ➹ ➹ ➹ Excel VBA & Macros ► http://bit.ly/LeilaVBA Excel Dashboards ► http://bit.ly/LeilaDashboards Excel Charts ► http://bit.ly/LeilaCharts Advanced Excel ► http://bit.ly/LeilaAdvancedExcel Excel Waterfall Charts ► http://bit.ly/LeilaWaterfall 🕮 Recommend Excel Resources 🕮 https://www.xelplus.com/resources/ ✉ Subscribe to my Newsletter ✉ Stay informed and get discounts when new courses come out: http://www.xelplus.com/

Linear Algebra 11y: The Transpose of a Triple Product
 
02:33
This course is on Lemma: http://lem.ma Lemma looking for developers: http://lem.ma/jobs Other than http://lem.ma, I recommend Strang http://bit.ly/StrangYT, Gelfand http://bit.ly/GelfandYT, and my short book of essays http://bit.ly/HALAYT Questions and comments below will be promptly addressed. Linear Algebra is one of the most important subjects in mathematics. It is a subject with boundless practical and conceptual applications. Linear Algebra is the fabric by which the worlds of geometry and algebra are united at the most profound level and through which these two mathematical worlds make each other far more powerful than they ever were individually. Virtually all subsequent subjects, including applied mathematics, physics, and all forms of engineering, are deeply rooted in Linear Algebra and cannot be understood without a thorough understanding of Linear Algebra. Linear Algebra provides the framework and the language for expressing the most fundamental relationships in virtually all subjects. This collection of videos is meant as a stand along self-contained course. There are no prerequisites. Our focus is on depth, understanding and applications. Our innovative approach emphasizes the geometric and algorithmic perspective and was designed to be fun and accessible for learners of all levels. Numerous exercises will be provided via the Lemma system (under development) We will cover the following topics: Vectors Linear combinations Decomposition Linear independence Null space Span Linear systems Gaussian elimination Matrix multiplication and matrix algebra The inverse of a matrix Elementary matrices LU decomposition LDU decomposition Linear transformations Determinants Cofactors Eigenvalues Eigenvectors Eigenvalue decomposition (also known as the spectral decomposition) Inner product (also known as the scalar product and dot product) Self-adjoint matrices Symmetric matrices Positive definite matrices Cholesky decomposition Gram-Schmidt orthogonalization QR decomposition Elements of numerical linear algebra I’m Pavel Grinfeld. I’m an applied mathematician. I study problems in differential geometry, particularly with moving surfaces.

AES Encryption 3: MixColumns 1 Dot Products
 
38:16
This video is on the MixColumns step in the inner loop of AES. Most of the topic for today is on how to manually multiply Galois fields, reduce them mod some polynomial, and add them together to compute a dot product. This is an important step in the construction of several look-up tables which form the basis of the mix columns step. We will eventually do the multiplication and reductions via a handful of lookup tables. This video does not present the entire MixColumns step but the rest is a little simpler once we look at dot products. This has been a tricky one to upload, I had it as one vid, but it was too long. So I split the matrix multiplication part to a separate vid. Hopefully, it's better that way.

Herschel Bulkley Parameters Calculator
 
06:33
Hello everyone, In this video, I am trying to explain how to calculate the rheological constants for herschel bulkley fluids for more than one data in an automated way. First of all, lets assume we have the data set as shown here, for 600,300,200,100,6 and 3 rpm from Fann 35 viscometer. Looking at the rheological model page, as you can see, there are two different plots. The first one, is the dots, which is the measured values and the second one is the estimated values from the rheological constants. Our aim is to have a minimum dot product between these two columns. So, to do this task, first we need to check some parts of excel. First, we should make sure excel solver is activated. If not, you can go to Tools / Excel Add-ins and activate it. Secondly, we should save this excel file as macro enabled file. Once they are both done, we can start recording our macro. Here, we are copy-pasting all the values one by one and then use the solver function to have a minimum dot product value by changing the rheological constants. Our first inputs in these constants are 0.5 for each which are just some random values. As you can see, right now we have a good match with our calculations and measurements. Next step, again we are copy-pasting these values to the main page of our excel. Afterwards, to repeat these steps automatically, we need to change some areas in our macro. First, make sure solver is active in the VBA. You can check that from Tools/references part. Afterwards, we are adding the for and next commands. We change the columns A2-I2 as A & i - I & i so that each i will refer to different row. First of, lets test the macro for i = 2 to 5. As you can see, the solver is asking for approval each time. To fix that, we need another minor change. We are just going to add SolverSolve UserFinish: = True Trying again for i=5 to 10. As you can see, it is asking for approval anymore. Then we repeat the process for the rest of the rows and as you can see, it works perfect. In this video, we have tried to explain how to record a basic macro, how to make some minor changes on it and add a loop to it, how to make it work better with solver and last but not least, applying it on the calculation of Herschel Bulkley Fluid reology parameters. You can download this excel spreadsheet from the comments part of this video so that you dont even have to record and adjust the same steps anymore. Let me know if you have any comments/questions.

Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

Matrix Multiplication
 
00:42
Check us out at http://math.tutorvista.com/algebra/matrix-multiplication.html Matrix Multiplication The ordinary matrix product is the most often used and the most important way to multiply matrices. It is defined between two matrices only if the width of the first matrix equals the height of the second matrix. Multiplying an m×n matrix with an n×p matrix results in an m×p matrix. If many matrices are multiplied together, and their dimensions are written in a list in order, e.g. m×n, n×p, p×q, q×r, the size of the result is given by the first and the last numbers (m×r), and the values surrounding each comma must match for the result to be defined. The ordinary matrix product is not commutative. The element x3,4 of the above matrix product is computed as follows The first coordinate in matrix notation denotes the row and the second the column; this order is used both in indexing and in giving the dimensions. The element at the intersection of row i and column j of the product matrix is the dot product (or scalar product) of row i of the first matrix and column j of the second matrix. This explains why the width and the height of the matrices being multiplied must match: otherwise the dot product is not defined. The figure to the right illustrates the product of two matrices A and B, showing how each intersection in the product matrix corresponds to a row of A and a column of B. The size of the output matrix is always the largest possible, i.e. for each row of A and for each column of B there are always corresponding intersections in the product matrix. The product matrix AB consists of all combinations of dot products of rows of A and columns of B.

You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others.
