Problem: I only have Matlab 7.2 :-(
I wonder that there's
no possibility in MatLab to do these kind of operations:
M(:,:)-V(1)
M(:,:)-V(2)
M(:,:)-V(3)
M(:,:)-V(4)
...
M(:,:)-V(end)
I guess it is a common problem...
All hope is not lost. you can download my genop.m from the FEX and use
it instead of bsxfun. It will be slower, but it will work and no data
will be copied.

genop(@minus,M,permute(V,[3 2 1]))
