Inverting each Submatrix of a Matrix

Hi

I have a matrix that is used to record submatrices, which are 2x2.

[A B C]
[D E F]
[G H I]

all are 2x2 and all these submatrices have to be inversed. I do not want to use for loop. Is there any way to do this efficiently?

Thanks

Do you have a cell array?

I do not use cells

If you have the image processing toolbox

im=randi(10,4)
out=blockproc(im,[2 2],@(x) inv(x.data))

Thanks for your reply, but when I run profiler, for loop seems to be more efficient.
