** Two-dimensional inverse discrete Fourier transform. **

** IFFT2(F) returns the two-dimensional inverse Fourier transform **

** of matrix F. If F is a vector, the result will have the same **

** orientation. **

** IFFT2(F,MROWS,NCOLS) pads matrix F with zeros to size MROWS-by-NCOLS **

** before transforming. **
