How can I set column of matrix divisible by 12

I have a matrix 'M(1715*3849)' I want to reshape it to a Matrix that the size of the column can divisible with 12. How can I do it?

Thanks in advance.

>> 3849/12

ans =

320.7500

Why do you want to do that, can you provide some context? There is no way to do it without removing values or adding empty values.

Yes, adding empty values.

It will append columns with nan value

M = rand(1715, 3849);
extra_columns = ceil(size(M,2)/12)*12 - size(M,2);
M = padarray(M, [0, extra_columns], nan, 'post');
size(M,2)/12

Result:

ans =

   321
