New issue 2756 by [email protected]: Implement MatrixFunction
http://code.google.com/p/sympy/issues/detail?id=2756
We need a class MatrixFunction, like MatrixSymbol that contains arguments,
so, e.g., we can differentiate with respect to them.
Also, when you do MatrixSymbol()(t), it creates a commutative Function (see
issue 440).
In [54]: A = MatrixSymbol('A', n, n)(t)
In [55]: x = MatrixSymbol('x', m, n)
In [56]: x*A
Out[56]: A(t)⋅x
In [57]: A*x
Out[57]: A(t)⋅x
In [58]: type(A)
Out[58]: sympy.core.function.A
This should either raise TypeError or create a MatrixFunction.
