Details

interp performs lowpass interpolation by inserting zeros into the original sequence and then applying a special lowpass filter.

y = interp(x,r,l,alpha)

where

r increases the sampling rate of x (input data) by a factor of r. The interpolated vector y (Upsampled data) is r times longer than the original input x.

l is the filter length. The default value for l is 4.

alpha is the cut-off frequency, a floating point value in the interval [0, 1], inclusive of 0 and 1. The default value for alpha is 0.5.
