Rearranging rows into columns

Good day everyone,

I have searched forums and I could not find a suitable solution so I come here to post my question. I have a 1x152 array. I would like to turn this into a 8x19 array. Therefore shifting or moving every 19 data inputs into a new row. Here is a smaller example of what I am trying to accomplish

if true
  % code
A=[1 2 3 4 5 6 7 8 9 10 11 12 13 14 15]
end

I want to reshape, modify, move (or whatever term you wish to use) matrix A in order to obtain Matrix B which is

if true
  % code
B =

     1     2     3     4     5
     6     7     8     9    10
    11    12    13    14    15
  end

Any advice on how to do this would be greatly helpful to me. I will post the answer in my post with pictures in order to help anyone else who might have this issue.

Thank you

You indeed use the reshape function:

B = reshape(A, [], 3)';

produces your ‘B’ matrix.

Perhaps with an array transpose , as we don't know what kind of data they will be working with:

B = reshape(A, [], 3).';
