How to give a Function a latex representation?

[G B]

Hi--

I can give a symbol a latex representation with:

x1=symbols(r'x_{1}')

How do I create a function with a latex representation?

Ic=symbols(r'I_{C}',cls=Function)

Ic=Function(r'I_{C}')

Don't seem to work... They pretty print as strings.

Thanks--

Interesting.  

Function('V_{C}')

returns a string (V_{C})

Function('V_{C}')(t)

returns proper latex.  It must be how it's handled in the printer...

If you want to do anything nontrivial, you'll need to define a latex
printer on it, by defining _latex(self, printer) (where printer will
be the printer class that you should use to recursively print the args
with printer.doprint(expr)). See
http://docs.sympy.org/latest/modules/printing.html. Search the SymPy
code base for some examples.
