A matrix is a two-dimensional, rectangular array of data elements arranged in rows and columns. The elements can be numbers, logical values (true or false), dates and times, strings, …

MATLAB is an abbreviation for "matrix laboratory." While other programming languages mostly work with numbers one at a time, MATLAB® is designed to operate primarily on whole …

This example shows basic techniques for creating arrays and matrices using MATLAB.

This example shows basic techniques and functions for working with matrices in the MATLAB® language.

You can create a multidimensional array by creating a 2-D matrix first, and then extending it. For example, first define a 3-by-3 matrix as the first page in a 3-D array.

You can use the randperm function to create a double array of random integer values that have no repeated values. For example, create a 1-by-5 array containing integers randomly selected …

This topic contains an introduction to creating matrices and performing basic matrix calculations in MATLAB ®. The MATLAB environment uses the term matrix to indicate a variable containing …

To create block arrays and perform a binary operation in a single pass, use bsxfun. In some cases, bsxfun provides a simpler and more memory efficient solution.

X = zeros(sz) returns an array of zeros where size vector sz defines size(X). For example, zeros([2 3]) returns a 2-by-3 matrix.

This MATLAB function returns a square diagonal matrix with the elements of vector v on the main diagonal.
