if I have a function that outputs a new matrix which shift the input matrix columns from 1 index how can I perform this operation with a for loop?

Illustrate with an example.

Hi,

Say your input matrix(t) is an n*m matrix.

for i = 1:n
    for  j = 1:m
    s = t(i,j);
    t(i,j) = t(i,j+1);
    t(i,j+1) = s;
    end
end

The above code will shift the first element of each row to the last.

The same can be performed without a loop.

s = t(:,1);
t(:,1) = [];
t(:,n) = s;

I hope it was helpful

Regards
