Print latex formatted matrix from ipython notebook

[brombo]

Is there anyway to print a nicely latex formatted matrix in ipython notebook?  When I try I just get the test version printed out while the latex formatting for the other objects I am printing works fine.

I should clarify what I am doing.  I have custom latex printers for Matrix, Derivative, Function, Pow, and Symbol.  All work fine when generating a tex file for input to pdflatex.  Except for Matrix all work fine in printing latex in "ipython notebook."  I don't know what is different about Matrix.  Note that in my initialization for latex printing I have the statements -

Basic.__str__ = lambda self: GaLatexPrinter().doprint(self)
Matrix.__str__ = lambda self: GaLatexPrinter().doprint(self)
Basic.__repr_ = lambda self: GaLatexPrinter().doprint(self)

I added -

Matrix.__repr__ = lambda self: GaLatexPrinter().doprint(self)

but it made no difference in the output.

With the information you provided, I can only try a guess.

Have you checked if __repr__ gets overwritten by __new__ in either Basic or Expr? SymPy's printer code is usually defined in the printing system files, not in the classes themselves.
