[Q] FindRoot & large system of eqns
Posted:

I am a new user of the student edition of mathematica. I am trying to use it to solve a large system of nonlinear equations using FindRoot in the form of:
FindRoot[{eqn1==something,eqn2==somethingelse,...},{x1,0},{x2,0}]
I have 16 equations and 16 unknowns, as is required, but it seems no matter how many of the system variables that I provide initial guesses for, mathematica always seems to state that my system is somehow not properly defined, guessed for...etc.
Does someone have a good, straightforward example for FindRoot applied to a large nonlinear system? If so, please email it to me at

Thanks in advance Anthony Egan Masters Student of Chemical Engineering South Dakota School of Mines and Technology
