how to calculate the right null space of a matrix in matlab

To find the right null space of a matrix in MATLAB, you can use the null function. This function calculates a set of orthonormal basis vectors for the null space of the input matrix. Here is an example of how to use it:

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

% Calculate the right null space of A
N = null(A, 'r');

% Display the result
N

The 'r' input for the null function specifies that we want to calculate the right null space (as opposed to the left null space). The output N contains the orthonormal basis vectors for the right null space of A.
