Template Nightmare

[Michael]

Hi guys,
I'm trying to use the JAMA libraries which are a templated set of classes,
but my experience in templated classes is limited.
Now, htis is the definition according to the lib's DOxygen breakdown:


template<class Real>
JAMA::Eigenvalu e<Real>::Eigenv alue<Real> ( const TNT::Array2D< Real >
& A ) [inline]



and I try to invoke it with:




TNT::Array2D<do uble> CovarMatrix(3,3 ,0.0);

//(Do stuff to Covar)

JAMA::Eigenvalu e<double> EV(CovarMatrix) ;



but the compilers not having any of it. Could someone please expain the
above notation to me.

Many Thanks



Mike

Care to be a bit more specific? What is the error you are getting?

Compiler is telling you that <tnt_math_utils .h> is incompatible with
<xutility> in the same namespace. Are you using "using namespace ..." in
your code? If so, don't!

Let me guess. You're including <windows.h> as well, aren't you?
Microsoft has done the very evil thing of #define'ing min() and max().

In your project properties, add /DNOMINMAX, or in your stdafx.h file (as
the first non-cmment line) #define NOMINMAX

This suppresses the evil redefinition of min and max.

Many thnaks guys, I'm back in business.. it was the "using namespace std"
that it didn't like so much!
