* matrix.h - misc. routines for manipulating matrices and solving linear
* equations. Matrices are assumed to be declared as **double and
* allocated by the function MatrixAlloc. A matrix can be freed by
* MatrixFree. Similar for vectors.

* $Log: matrix.h,v $
* Revision 1.1 2006/06/20 15:57:22 djburke
* Hopefully a saner way to build Basic/MatrixOps
*
* Revision 1.1 2005/01/08 09:22:57 zowie
* Added non-symmetric matrices to eigens; updated version to 2.4.2cvs.
*
* Revision 1.1.1.1 2001/07/06 13:39:35 kneth
* Initial import of code.
