Broyden's Method (假牛顿法)
可以"省下" 换case需要找Jacobian的麻烦
解多维度
Broyden's Method
Broyden's method is a robust alternative to Newton's method for solving
systems of nonlinear equations. A C version of Broyden's method is available
on this site. The 'zip' archive includes the Broyden solver, a supporting
Gaussian elimination linear solver, and a simple test program.
A complex version of Broyden's method has also been created. Complex Broyden
solvers appear to be fairly rare, as I have been unable to find any other
versions elsewhere. This archive includes the complex Broyden solver, a
supporting complex Gaussian elimination linear solver, and a simple test
program.
有兴趣或需要的 可以抓来使用看看
以大家coding的能力 要移植到自己适用的程式上 应该都是小case
如果还不太懂 可以找我讨论搂 哈
他是C++ code 所以要 include <iostream.h>
