Perfect sinc interpolation in Matlab and Python

	% From http://phaseportrait.blogspot.com/2008/06/sinc-interpolation-in-matlab.html

	% Ideally "resamples" x vector from s to u by sinc interpolation
	function y = sinc_interp(x,s,u)
	% Interpolates x sampled sampled at "s" instants
	% Output y is sampled at "u" instants ("u" for "upsampled")
	% (EXPECTS x, s, and u to be ROW VECTORS!!)

	% Find the period of the undersampled signal
	T = s(2)-s(1);
