How it works?

It uses Newton's method for solving equations. Required Jacobian matrix is evaluated numerically at each iteration. It also uses a special technique which maximizes speed by reducing a large problem into smaller problems with less number of variables.

Where to use?

Solving equations can have many applications in engineering and sciences. phpEquations can be used for solving equations in web applications written in PHP.

How to use?

phpEquations can be used in PHP codes as follow:

1. Include phpequations.php class in codes. This may be required only once.
2. Declare object as phpequations and call object's function solve(equations).

Results of function are obtained as array ([variable]=>value).
