Re: Is there a mathematical matrix class?

[Fred Kiefer]

NSMatrx is OK for what it was designed for, 2D affine transformations. But what 
you are asking for is more like a general propose mathematical matrix 
implementation. I don’t know anything like this for Objective C. What you could 
try is to take a C++ matrix implementation and wrap it into an Objective-C 
class.

Cheers,
Fred
