Hey I wrote a function that the user enters a matrix, and the function returns "1" if the matrix is reversible(regular) and "0" if it's not.
I wrote this function-
function x=irr_mat(A)
n=size(A)
if isequal(A,zeros(n))
x=0;
else
if size(A,1)==size(A,2)
x=1;
else
x=0;
end
end
end
and i call the function -
A=randi([0,100],4);
irr_mat(A)
and get -
n =
4 4
ans =
1
I need to get matrix with 4X4... what is the problem?

What you entered is 4x4 matrix....so the answer 1, is correct. I am surprised what you are trying to achieve.

This is at least the second follow up question. Do not post a new question about the same topic if you are not happy with the response you're getting. Ask for clarification instead.
