Could someone help me with my problem.
I've got an original 2 by 25 matrix and I want to create a new 2 by 25 matrix with the same columns than the original one. But I want them reorganized such that a given column (:,n) in the new matrix is different from the columns (:,n:n+2) of the original matrix.
I've struggled to do that as Ifind a way using loops that need a lot of if statement to control for special cases... Is there someone with a simple(r) method to do that?

You can try the function diff:
A = magic(5);
B = diff(A,[],2)
But B will have n-1 column what do you want for the extra column ?
