LAPACK++

LAPACK++, the Linear Algebra PACKage in C++, is a software library for numerical linear algebra that solves systems of linear equations and eigenvalue problems on high performance computer architectures.

It supports various matrix classes for vectors, non-symmetric matrices, SPD matrices, symmetric matrices, banded, triangular, and tridiagonal matrices. However, it does not include all of the capabilities of original LAPACK library.

History

The original LAPACK++ (up to v1.1a) was written by R. Pozo et al. at the University of Tennessee and Oak Ridge National Laboratory.However, in 2000 R. Pozo et al. left the project, with the projects' web page stating: "This package is being superseded by the Template Numerical Toolkit (TNT)." Unfortunately, the TNT project never really took off.

The current LAPACK++ (versions 1.9 onwards) started of as a fork from the original LAPACK++. There are extensive fixes and changes, such as more wrapper functions for LAPACK and BLAS routines.
