Is there a two-dimensional sinc interpolation software?

Since interpolation is commonly approximated by cubic spline interpolation, which you have an option for in interp2.
Vq = interp2(X,Y,V,Xq,Yq,'spline');

We know that Fourier is a seperable transform... so if we want to do a Fourier 2D transform its equivalent to doing 1D transform on rows and then columns. I assume then this property holds for sinc interpolation... So I adapted the 1D example for sinc interpolation they provide on the sinc(x) documentation ... and then I applied the interpolation to the rows and then interpolation to the columns and it seemed to work
