How to transpose certain elements in a matrix

Hi,

I have 5by5 matrix, A:

0 9 2 0 0

0 0 0 1 0

0 3 0 5 0

0 0 0 -3 0

0 0 -1 8 0

where I want to transpose only the positive numbers.

Note: The corresponding transposed location is always zero.

so the answer should look like this, B:

0 0 0 0 0

9 0 3 0 0

2 0 0 0 0

0 1 5 -3 8

0 0 -1 0 0

Thanks a lot for your help :)

B = A.*(A<0) + (A.*(A>0)).' ;

That was very efficient and neat. Thank you so much :)
