I am trying to watch difference between cubic interpolation and spline interpolation using matlab plot but i am getting same plots in both cases using interp1 command
My code is below. In below code ,if i use spline in place of cubic, i still exactly get same plot,why?
clcclear allclose allx = 0:pi/4:2*pi; v = sin(x);xq = 0:pi/16:2*pi;vq2 = interp1(x,v,xq,'cubic');plot(x,v,'o',xq,vq2,':.');
