Up/down sample an image/matrix/vector (can be of complex numbers) using the frequency domain.
The matrix/vector should be continuous of a high degree (has continuous derivatives) in order to obtain a reasonable up/down sampling

Speed-up can be achieved if the user up-samples to a near power of 2. no optimization is done inside this code for efficient fft usage.

Documentation is found inside the *.m file.

type "updownsample" for the example

I found a linear phase distortion in the output image (only when looking at a complex or real output image), due to spatial misplace of the input image in the fourier domain
