Rearranging values in a matrix

I have a matrix that has 4 columns and I would like to rearrange it to have 5 columns so that the value in the second row first column becomes the value in the first row fifth column. So if the matrix was:

[1 2 3 4
5 1 2 3
4 5 1 2 
3 4 5 1 
2 3 4 5]

It would become:

[1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5]

Does anybody know how I could do this? Thanks in advance!

Suppose your initial matrix is called oldMat:

reshape(oldMat', [5, 4])'

It is a good habit to use non-conjugate transpose:

reshape(oldMat.', [5,4]).'

Thanks for the tip.
