Is there any Matrix in the STL?

[DeMarcus]

Hi,

Is there any kind of "std::matrix<>" in the STL that is optimized
for matrix operations, or do I have to do a
std::vector< std::vector<someType> > myMatrix;

Best regards

Daniel

IMO, multiple dimension arrays in C and C++ are a pain in the ass, an
issue that should have been addressed way earlier. Luckily boost
(www.boost.org) has a multi_array that is likely to meet your needs.

For 2d arrays, also have a look at uBLAS (also at boost). This also
mentiones other math-libraries that may offer other advantages, most
notably Blitz++.

Try to use the Blitz++ library for maximum performance and usability.

You might also want to have a look at the Matrix Template Library at

The valarray class templates are the closest to what you want.

Take a look at The Object-Oriented Numerics web page:

http://www.oonumerics.org/oon/

In particular, take a look at
The C++ Scalar, Vector, Matrix and Tensor class Library
