Rearrange matrix into single row

Hey there, I have a matrix that looks like this

    b=1 2 3 4
      1 2 3 4
      1 2 3 4

What do I have to do to arrange it into a single row vector[ 1 2 3 4 1 2 3 4 1 2 3 4]?

reshape(b',1,numel(b)) % Note the transpose ('), this is important.

This answer uses complex transpose. See James Tursa's answer for the correct solution for all cases.

Answer 2

[James Tursa]

result = reshape(b.',1,[]);

The transpose is needed to get the row values to line up in memory first before doing the reshape.
