Hello, how can I eliminate the nullspace of a square matrix using Matlab? Thank you!

If you want a basis of the row space of A, use orth(A.').
The rule is that
null(A) + orth(A.') = R^n
where n is the dimension of your matrix.

If you have any matrix, square or not, you have only one possibility: remove entire rows or columns that are equal to zero
A=[1 2 3 0;0 0 0 0;1 4 5 0 ;2 7 8 0]
