pear install Math_Matrix-0.8.5
Try PEAR2's installer, Pyrus.
php pyrus.phar install pear/Math_Matrix-0.8.5
For manual installation only
Release date: 2003-11-01 19:15 UTC
Release state: beta
Fixed some bugs in matrix multiplication reported by John Pye
(firstname.lastname@example.org) and Marcel Brunner (email@example.com).
Fixed some minor documentation incosistencies.
Modified the setData() method to accept a Math_Matrix object or
an array of arrays of numbers.
Added the setZeroThreshold() and getZeroThreshold() to set and get the
value used as upper bound to minimize round-off errors.
Added also two static methods to generate famous matrices:
Math_Matrix::makeHilbert() for a square Hilber matrix, and
Math_Matrix::makeHankel() for m by n Hankel matrix.
Reorganized the directories to comply to the current directory organization
It is recommended to uninstall the older version of Math_Matrix (and
Math_Vector) before installing this new release to avoid lingering files
(there is also a new release of Math_Vector):
$ pear uninstall Math_Matrix Math_Vector
$ pear install Math_Vector
$ pear install Math_Matrix
Included explicitely the optional dependency on the PHPUnit package version
0.6.2 or older, as current versions of that package need PHP5.
