General Non Linear Equation Solver

This is a basic quasi-Newton solver. It uses finite differencing to estimate dervatives.

• Enter the equations in the left hand box using the syntax of the example. Variables must be called x1, x2, etc.
• Each new equation should be on a separate line, with functions on the left and zeros on the right hand side.
• Click `INITIALISE' to generate blanks for all guesses.
• Click `Solve'
• If a solution is found, it will appear in the right hand box.
