C++ library for numerical computing

[Jorn Attermann]

I perform numerical simulation which requires linear algebra programming
that is optimized for speed. However, to my surprise, there seems to be no
"standard" linear algebra library in C++ which is well documented, allround
and agreed upon as being effective.

I am currently using TNT (http://math.nist.gov/tnt/) which, however, lacks
some important methods such as conversion of a three-dimensional array
(Array3D) to a number of individual two-dimensional arrays (Array2Ds). I
have implemented my own methods but I feel far from assured that these are
optimal.

I would appreciate very much to hear the group's view on this.

Is Blitz++ relevant to your problem?

or any other language, for that matter,

Take a look at
The C++ Scalar, Vector, Matrix and Tensor class Library

http://www.netwood.net/~edwin/svmtl/

Also, take a look at the
Vector, Signal and Image Processing Library

http://www.vsipl.org/

and the
High Performance Embedded Computing Software Initiative (HPEC-SI)

Re: C++ library for numerical computing

The boost library has something called ublas, which contains a whole lot of
CBLAS and CLAPACK derived stuff.

I think some of it was inspired by Blitz++.

I'm not sure how it compares to other libraries.... any opinions?
