MATLAB: Swap columns of a matrix

Question

Hello guys/girls

How do i swap columns??

I have this

k_minus =

   -46   -43   -26   -14     7    19    11    32    39    45    45
     0    -4    -7    -7   -44   -44    -7    -7   -15   -15     0

and I want the columns to be in opposite order – How do I do this? and can do this in one go?

Answer 1

You could also use

 out= fliplr(k_minus)

This flips the matrix left-right http://www.mathworks.com/help/matlab/ref/fliplr.html
