What is the corresponding function for corrmtx (in MATLAB) in Python?

Question

I'm translating some code from MATLAB to Python and I'm stuck with the corrmtx() MATLAB function. Is there any similar function in Python, or how could I replace it?

Answer 1

Here is a list of alternatives that can help you in translating your code, all of which contain that function:
scipy (toeplitz | corrmtx)
spectrum (corrmtx)

The following is a link to another post that tells you how to use numpy for the auto correlation since it seems to be the default funcationality of corrmtx

Answer 2

How about:

http://docs.scipy.org/doc/scipy/reference/generated/scipy.linalg.toeplitz.html

The matlab docs for corrmtx state:

X = corrmtx(x,m) returns an (n+m)-by-(m+1) rectangular Toeplitz matrix X, such that X'X is a (biased) estimate of the autocorrelation matrix for the length n data vector x.

The scipy function gives the Toeplitz matrix, although I'm not sure if the implementations are identical.

Answer 3

The spectrum package has such a function.
