This code was inspired by Alexander Huth's bilinear interpolation approach
( http://www.mathworks.com/matlabcentral/fileexchange/20248 )
also using the GPU's built-in bilinear texture interpolation capability, which is indeed very fast.

The speedup is depending on your CUDA enabled graphics hardware. The more multiprocessors, texture units, ... the better the results will be.

In comparison to Alexander's cudainterp2, I added some performance improvements and the capability to interpolate complex numbers too.

Feel free to write some feedback or a comment.
