non linear equations

Hi,

I am trying to find out the complex root of a very large non-linear equation involving bessel functions. What is the best-suited numerical method?? Will bisection method be helpful in finding complex root? ... I tried it, but does not give me the proper result...
pls help me... urgent.


Thanks.

Re: non linear equations

I would recommend the Newton-Raphson Method: to solve f(x)= 0, construct the sequence . That will typically converge fairly rapidly to a root. One advantage it has over bisection is that you do not have to find two values of x that you know have a root between them- although, the closer you choose to a root, the faster the sequence will converge.

Re: non linear equations

There are plenty of methods that are available for you to solve these type of equations Newton Raphson, Gauss elimination, Gauss-Seidel, Newton forward interpolation formula, etc.
If you have linear equations, then I would like to tell you that you can use a linear equation solver for solving them.
