Hello,

I would like to define an action, let us say:

def Ac(Y,k):
    return k.transpose()*Y*k

where Y and k are square matrices of the same size.

But, I would prefer to use a more mathematical notation, like Y[k] or
y...@k or whatever non already used symbol instead of Ac(y,k).

How is it possible to do that?

Best regards.

Drenwal
