Convert Matrix to String in MATLAB using `mat2str`

This article explains how to convert a 2D matrix into a string format with MATLAB syntax using the mat2str function.

The mat2str function in MATLAB is a handy tool for representing numerical matrices as strings. This can be particularly useful when you need to store matrix data in text files, transmit it across systems, or simply display it in a human-readable format that includes the standard MATLAB matrix notation.

mat2str MATLAB Function

The basic syntax is quite straightforward:

output = mat2str(A)

Where A is the input matrix, and output will be the string representation of that matrix.

Example

Let’s illustrate with a simple example:

A = [1 2 3; 5 6 7; 9 10 11; 13 14 15];  % A is the matrix
output= mat2str(A)

The resulting output variable will contain the following string:

[1 2 3;5 6 7;9 10 11;13 14 15]

As you can see, the matrix A has been converted into a string that reflects the matrix structure and its elements within square brackets, with rows separated by semicolons.
