c++ and linear algebra

[jeremytaylor]

Hi,
I do a lot of numerical/computational linear algebra and until now I have relied on fortran90/95 and BLAS/LAPACK/Scalapack. However I'm currently trying to tackle a problem that would benefit from some object oriented goodness and so would like to code it in C++. Does anyone have any recommendations for linear algebra packages for c++? I have tried google and there seem to be a wealth of options but I'm unsure which to pick.

Any advice would be much appreciated.

FORTRAN can do OOP, not as elegant as C++ yet, but it is possible.

I thought LAPACK abd BLAS have C++ bindings.

http://math.nist.gov/tnt/index.html looks suitable.

Take a look at the Boost uBLAS library. Not as fast as many FORTRAN implementations, but they are working on wrappers so you can have the best of both.

I thought LAPACK abd BLAS have C++ bindings.
The GNU Scientific library has implemented cblas (http://www.gnu.org/software/gsl/manual/html_node/GSL-CBLAS-Library.html), For lapack, there is clapack, which is simpply and f2c converstion. There is also lapack++, which is a c++ implementation.

I would recommend you check out atlas (http://math-atlas.sourceforge.net/) instead of using the f2c implementations.

Thanks everyone, I'll have a look at those.

Fortran can do OOPish :) I've written some and it's not pretty.
