Mapping two matrices

Hi! My question is :
I have two n x n matrices one being pressure levels(SPL) and the other one being the frequency (f) of each and every SPL. Their indices are of course the same since the matrices are identical in shape. I need to sort the f matrix and put it into a 1D vector form and I want the SPL matrix to follow.
How could I do this? Thanks

[fS, index] = sort(f(:));
out = [fS, SPL(index)];

out = [f(:) SPL(:)]
with sort
out = sortrows([f(:) SPL(:)],1);

Sorry, I should add the f matrix should be ascending. I mean any kind of operation I apply on f should effect SPL identically.
