Hi to all...
I have a serious problem concerning Broyden method of chapter 9. In my problem, there's a set of equations like this:
3*x-cos(y*z)-0.5=0
x^2 -81*(y+0.1)^2 + sin(z) +1.06 =0
Exp(-x*y) +20*z+ (10*pi -3)/3=0
And even when I execute Broyden using the routine lnsrch()...I have to be in a very very close position to the root for the convergence of the solution....What's the problem then? I expect your help, please. And sorry for my bad english.
Yours, Galego.
