Matlab-like Matrix-constructor for Python's sympy

Mtrix.py

import sympy as sp

def Mtrix(matrix_def):
    '''
       Constructs a Sympy Matrix from the string matrix_def that has a Matlab-like syntax:
       
       E.g.: Mtrix("a b c; d e f; g h i") creates a 3x3 matrix where [a b c], [d e f], [g h i] are the rows.
       
       Example: Mtrix("0 1/2 7; 3 -4 8; 17/3 4 87")
       
                returns the same matrix as ...
                
                sp.Matrix([[0, "1/2", 7], [3, -4, 8], ["17/3", 4, 87]])
                
                would do
    '''
    return sp.Matrix([line.strip().split(' ') for line in matrix_def.split(';')])
