'm' is not defined

[dimdim89700]

Hello,

I am trying to learn to use SSA and I wanted to use your tutorial to see how to use it and how ti works. But when I tried to use your code I get an error message :

" File "...\pssa-master\src\mySSA.py", line 91, in embed
self.X = m(linalg.hankel(self.ts, np.zeros(self.embedding_dimension))).T[:,:self.K]
NameError: name 'm' is not defined"

In mySSA, in embed, in several lines, there is a 'm', that is not defined. Could you tell me how to defined it ? Or at least explain what it does please ?

Thanks in advance
