Description

Programs to transpose and invert matrices, to solve linear equation systems, to compute the eigenvalues and eigenvectors of symmetric matrices, and to compute bipartite matchings with the Hungarian method. A brief description of how to apply these programs can be found in the file matrix/ex/readme in the source package.

The modules of this package are also needed for compiling, for instance, the regression program, the neural network programs, and the clustering programs. Note that this library of matrix functions is incomplete: eigenvalue and eigenvector functions for non-symmetric matrices as well as several other functions are still missing.
