How to reshape matrix in this way?

Hello everyone,

I was wondering if anyone could help me in a simple question in matrix reshaping.

I have a 3x4 matriz M, as it follows:

M = [1 2 3 4;
     5 6 7 8;
     9 10 11 12]

I would like to reshape M to have the following matrix N:

 N = [1 2;
      3 4;
      5 6;
      7 8;
      9 10;
      11 12]

I have tried 'reshape' command, but failed. Can anyone please help?

Thanks in advance!

N = reshape(M.',2,6).';

You need to transpose first (and later back again), because the reshape command works down the columns.

Thank you so much for your fast answer! I wasn't transposing twice. Now it worked! =)

Hello, Try this:

Answer = reshape(M.',2,[]).';
