Is there a good PHP library for vectors and matrices? [closed]

Answer 1

There is this library:

https://sourceforge.net/projects/phpmatrixlib/

it contains matrix multiply, inverse, transpose and determinant

Answer 2

There is

• http://pear.php.net/package/Math_Matrix and
• http://pear.php.net/package/Math_Vector/

and a number of other related PEAR packages about Math

• http://pear.php.net/search.php?q=math&in=packages&x=0&y=0&p=1

I do not know if they suit your needs though. See for yourself.

Answer 3

There used to be a PHP4 port of the JAMA matrix library at http://www.phpmath.com but it seems to have disappeared from the site. We use it in PHPExcel (though I've updated it a bit to PHP5)
