I have a 1by79 array and want to interpolate to a 1by84 array. Is there a way to do this? I checked interp1 (<http://www.mathworks.com/help/matlab/ref/interp1.html>) but don't know how to use this function in my case. Or other ways to achieve my goal? Thank you.

t = linspace(1,10,79);
x = sin(t);
ti = linspace(1,10,84);
xi = interp1(t,x,ti);
plot(t,x,'r.',ti,xi,'b.')

What if I wanted to interpolate in a smaller vector size, say 1by50?
Thanks in advance
