New issue 3217 by [email protected]: simultaneous substitution for
matrices
http://code.google.com/p/sympy/issues/detail?id=3217
Since issue 3145 subs has a simultaneous keyword, but this is not
understood by Matrix instances.
In [1]: e=x*y
In [2]: e.subs({x: y-1, y:x-1}, simultaneous=True)
Out[2]: (x - 1)*(y - 1)
In [3]: e=Matrix([e])
In [4]: e.subs({x: y-1, y:x-1}, simultaneous=True)

TypeError: subs() got an unexpected keyword argument 'simultaneous'
