How to interpolate a set of complex numbers in Matlab

Hi! I want to interpolate a set of complex numbers, which correspond to the Fourier coefficients of a signal obtained at a very big resolution (small frequency) in the laboratory. The reason is that I would like to extract from this huge vector only the coefficients at multiples of a bigger frequency. I was wondering if there is a way to do this in Matlab...I would really appreciate any help! Best regards

Use the interp1 function. See the documentation on Interpolation of Complex Values for details.
