Some posts about NumPHP and the current development

Today I have released NumPHP 1.0.2.
I have added the Cholesky decomposition.
It factors a matrix into a lower and a upper triangular matrix like the
LU Decomposition.
The disadvantage is, the Cholesky decomposition works only for symmetric positive definite matrices. The advantage is,
it is faster than the LU decomposition and the resulting matrices are *L* (*lower triangular*) and
*L ^{T}* (

Today I have released NumPHP 1.0.0-dev7. It contains the possibility to calculate the inverse of an invertible matrix in PHP. With a small example I would like to show how to use this function.

I have released NumPHP 1.0.0-dev3.
With this release I have added the LU decomposition.
Now you can factor every matrix in a *lower* and a *upper*
triangular matrix.
And a permutation matrix.

I would like to show, how to solve a system of linear equations in PHP with NumPHP.
