get the rref of a matrix in matlab

To get the row-reduced echelon form (rref) of a matrix in Matlab, you can use the built-in function rref(). Here's an example code snippet:

main.m
% define the matrix
A = [1 2 3; 4 5 6; 7 8 9];

% get the rref form of the matrix
rref_A = rref(A);

In this example, the original matrix A is defined as a 3x3 matrix. The rref form of the matrix is then calculated using the rref() function and stored in the variable rref_A.

You can then display the rref form of the matrix by simply typing rref_A at the command prompt.
