ifftshift() - Image Processing

ifftshift(X) swaps the left
and right halves of the vector X. For matrices, ifftshift(X) swaps
the first quadrant with the third and the second quadrant with the
fourth. If X is a multidimensional array, ifftshift(X) swaps
"half-spaces" of X along each dimension.ifftshift(X,dim) applies
the ifftshift operation along the dimension dim.Note:  


ifftshift undoes the results of fftshift.
If the matrix X contains an odd number of elements, ifftshift(fftshift(X)) must
be done to obtain the original X. Simply performing fftshift(X) twice
will not produce X.
