nsolve does not accept starting vector of type Matrix

[yashabk]

nsolve gives a TypeError when given a Matrix for the starting vector, requiring instead a manual conversion to a list via v0.T.tolist()[0]. Notably, nsolve is fine with a Matrix expression for the equation.

A minimal example:

import sympy as sy
v = sy.Matrix(sy.symarray("v", (2,)))
w = sy.Matrix([17, 23])
equation = v - w

The following line gives a TypeError: cannot create mpf from Matrix([[17],[23]]):
sy.nsolve(equation, v, w)

The following line gives the correct output, Matrix([[17.0],[23.0]]):
sy.nsolve(equation, v, w.T.tolist()[0])
