newton-raphson 迭代和雅各比矩阵计算方法

Newton with Numerical Jacobian

Usage: Newton(@funfcn,X0[,Options[,Params]);

funfcn is a function script with the following interface:

function F = function(X)

% ...

or a string containing the code as shown below,

were F is the vector of the functions, and X the vector of the

unknowns which must have the same length.

A guess for X must be specified in X0.

Options.bVerbose prints iteration history

Options.nMax maxsteps limits the number of iterations

Options.eMax maximum allowed error

Params vektor or structure of parameters handed over to the function-file. In large models a global structure should be preferred.
