Hello! To begin to ask for excuses you for my English poor level... I am a Spanish student of Chemical Engineering. Now I am employed at the simulation of a series of chemical reactions with Mathematica.
As soon as I have programmed the problem to resolving, 23 equations with 23 variables, I use the function Nsolve, but the program returns to me the following message of mistake
General::ivar: 0 is not a valid variable. >>
I have programmed my problem of the following form:
ecu{lhs1==0,lhs2=0,...,lhs23}
sol=Nsolve[ecu{var1,var2,...,var23}]
Might someone help?
Thank you very much!
Jorge
