Correlation utilities (`pydsm.correlations`)

Functions to compute the auto- and cross- correlation between two vectors.

So far only unnormalized (raw) correlations are supported.

Functions

`raw_acorr`(x, N)	Computes the raw autocorrelation of a vector up to lag N.
`raw_xcorr`(x, y, N)	Computes the raw crosscorrelation between two vectors up to lag N.
