I have a raw signal as a vector.
I have a smoothed signal derived from the raw signal with an
in-house algorithm. (It is another vector.)

I need to quantify the variance of the smoothed signal from
the raw signal. What are some good options for this in Matlab?

Also, as a second question, if I want to quantify the noise
in the raw signal (referenced to itself only), what Matlab
functions should I look at?

Thanks
