Release date: 2003-11-01 19:15 UTC Release state: beta Changelog: Fixed some bugs in matrix multiplication reported by John Pye (john@curioussymbols.com) and Marcel Brunner (marcel@palmer.li). 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 proposal. 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.
