Stretching data to fit a specific window

Hi all,

I have large amounts of data that are sampling at incorrect intervals. I want to compare the signals, but they don't properly line up because of the sampling rate. I want to be able to stretch or shrink the data to a specific number of samples, but maintain overall shape.

 x = linspace(0,2*pi,110);
 Y = sin(x);

 xi = linspace(0,10);

 yi = interp1(x,Y,xi);
 plot(xi,yi)

What I want out of this is one full cycle of a sin wave, but stretched from a period of 2*pi and 110 samples to a period of 10 with 100 samples even.

I'm sure there is an easy way to do this, but I've been racking my brain and can't seem to find a solution.
