Nothing I would know already does that. But the FunctionParser class
supports vector-valued functions, and it should not be very difficult to
write a little wrapper that is derived from TensorFunction, takes a
Function object as constructor argument, and simply interprets the
vector components returned by the latter as the tensor components of a
TensorFunction.
Of course, you could also copy FunctionParser to TensorFunctionParser
and make the relevant adjustments. That also should not be very difficult.
In either case, this would actually make for a nice addition to the library!
