in my php script i need to work with matrix. thus i found a great class on phpclasses.org.
it works fine, but when i like to calculate the inverse of a matrix it takes to much time, for example:
4x4 matrix needs ca. [url removed, login to view]
5x5 matrix needs ca. [url removed, login to view]
7x7 matrix needs ca. [url removed, login to view]
in my application for exmaple i have a matrix of 36x36 and there is still no matrix after 30min.
i found this site in the web:
<[url removed, login to view]>
when i copy my 36x36 matrix to there it only takes ca. 1 second. so i think there should be a better solution for that class. i think so, i do not know!
i have put the class with example in the attachment, then you can have a look at it.
i like to have this class back, but the calculation of bigger NxN matrix should be a lot of faster. i only want changes on the class, no strange stuff like zend optimization.
