While other programming languages mostly work with numbers one at a time, MATLAB® is designed to operate primarily on whole matrices and arrays. All MATLAB variables are …

You can set the format in either the Command Window or the Live Editor. Changing the format in one automatically updates it in both contexts.

This MATLAB function formats data values from the input array, A, using formatting operators specified by formatSpec and returns the resulting text in str.

To convert data to text and control its format, you can use formatting operators with common conversion functions, such as num2str and sprintf. These operators control notation, …

Create a matrix, write it to a spreadsheet file, and then read and display the contents of the file. Create a matrix in the workspace.

This MATLAB function converts a full matrix into sparse form by squeezing out any zero elements.

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.

This MATLAB function returns the rational fraction approximation of X to within the default tolerance, 1e-6*norm (X (:),1).

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

For example, when you declare a 3-by-3 matrix, the software stores this matrix as a one-dimensional array with nine elements. By default, MATLAB stores these elements with a …
