SymPy - substitute sybolic entries in a matrix

Question

I have a python function which generates a sympy.Matrix with symbolic entries. It works effectively like:

import sympy as sp
M = sp.Matrix([[1,0,2],[0,1,2],[1,2,         


        

Answer 1

Symbols are defined by their name. Two symbols with the same name will considered to be the same thing by Sympy. So if you know the name of the symbols you want, just create them again using symbols.

You may also find good use of the zip function of Python.
