We intend to use several smoothing techniques to smooth out some data. We have tried the following methods:

Gaussian-weighted moving average
Linear regression
Quadratic regression
Savitzky-Golay filter

All of them are giving very similar results, and it has been hard for us to decide which one would be the optimal technique to move forward with. Thus we would like to know if we can measure the computational efficiency of each technique while using them in Matlab and hence we can choose the most efficient one, since all of them are giving similar results.

So is there a way to achieve this?

Thanks in advance.
