I know Eureka, by Borland, for the IBM can do this. > A program for solving nonlinear multple equaitons is available on Wayne's mail server. It is very useful solving almost any system. The program is on the math directory with the name MULT.EQ.SOLVER or something like that. ====================================================================== ___ I__) _ _I _ _ TIM STRONG I \ (_I (_I (_I I MICHIGAN TECH.
