How to Transpose Data in Excel: Turn Rows into Columns (vice versa) Written by co-founder Kasper Langmann, Microsoft Office Specialist. Reorganizing data in a spreadsheet can be a pain. Especially when you have to make big changes that a simple copy-and-paste won’t fix. One of the common tasks that fall into this category is transposing: ie. turning rows into columns (or columns into rows).

The high-performance implementations of matrix multiplication is actually kind of strange: load 3 scalars from the left-hand-side matrix and broadcast them into full SIMD registers, then load 4 vector values from the right-hand-side matrix, and multiply all of them into 12 accumulation registers. This odd implementation is not something that the compiler can do for you automatically.

Correlation Matrix: An R Function to Do All You Need. The goal of this article is to provide you a custom R function, named rquery.cormat(), for calculating and visualizing easily a correlation matrix in a single line R code. Brief outline: Computing the correlation matrix using rquery.cormat() Upper triangle of the correlation matrix; Full correlation matrix; Change the colors of the.Fast 4x4 Matrix Inverse with SSE SIMD, Explained. Table of Contents. Transform Matrix Inverse; General Matrix Inverse; Appendix 1; Appendix 2; Before we start, think about this question: do we really need the inverse of a general matrix? I came to this problem when writing a math library for my game engine. If you are making a game or 3D application, we use 4x4 matrix for object transform.In R, the apply function allows you to apply a given function across all elements of a matrix. The t (transpose) function rearranges data in a matrix by exchanging its axes.

I am looking for C libraries supporting fast in-memory multicore integer matrix transpose, e.g.: long a(20000)(20000); libtranspose(a); This would be for a recent intel 6 core iMac under clang, but I am interested in what is out there for other architectures.

Read MoreSimple. A matrix is made up of rows and columns. Given a matrix with 3 rows and 3 columns: 1 2 3 4 5 6 7 8 9. After transpose you have: 1 4 7 2 5 8 3 6 9.

Read MoreA discussion on various ways to construct a matrix in R. There are various ways to construct a matrix. When we construct a matrix directly with data elements, the matrix content is filled along the column orientation by default.

Read MoreMatrix transpose is a fundamental matrix operation that arises in many scientific and engineering applications. Communication is the main bottleneck in performing matrix transpose on most multi-processor systems. In this paper, we focus on torus interconnection networks and propose application-level routing techniques that improve load balancing, resulting in better performance. Our basic idea.

Read MoreTranspose of a Matrix. A matrix which is formed by turning all the rows of a given matrix into columns and vice-versa. The transpose of matrix A is written A T. See also. Inverse of a matrix: this page updated 19-jul-17 Mathwords: Terms and Formulas from Algebra I to Calculus.

Read MoreCalculating eigenvalues and eigenvectors for age- and stage-structured populations is made very simple by computers. Here I show how to calculate the eigenvalues and eigenvectors for the right whale population example from class. The first thing we need to do is to define the transition matrix. Using the function c(), let’s put all of the entries in the transition matrix into one long vector.
