I actually joined this mathgroup because I had a question about this.
I am trying to solve fairly complicated integral problems using FindRoot to
figure out my coefficients. The code works without an error in 4.2 but in 5
I get an error about the function not being a real number when z=0 (which is
one of my integration variables) Basically same error.
F[x] for me is an NIntegrate of a least of 2 squares over a Region of
Interest.
Hd[B1_, B2_...]=Nintegrate[(Hz-1)^2,{zo,-L/2,L/2}]
Where Hz is a huge expression generated by the number of coeff's and my
kernel.
Hopefully this can be resolved because I really would like to use the
Conjugate Gradient Method built into FindRoot on 5.
I didnt notice the {x,{x0,x1}} change in the doc but thats not a real
problem.
Hopefully this can get resolved with a simple patch.
Jason
