Signal Toolkit - sampled2continuous

Function File: xt = sampled2continuous (xn, T, t)

Calculate the x(t) reconstructed from samples x[n] sampled at a rate 1/T samples per unit time.

t is all the instants of time when you need x(t) from x[n]; this time is relative to x[0] and not an absolute time.

This function can be used to calculate sampling rate effects on aliasing, actual signal reconstruction from discrete samples.
