 Author Comment/Response Revathi 09/11/00 5:53pm I have to solve for 16 unknowns with 16 equations, which should be easy to do. In fact, I did it easily by hand and on matlab, but I have to do it on Mathematica for a class and I'm having trouble doing it. Here's what I tried:--First, I tried using the Solve command to solve for all 16 unknowns at the same time. But it gave me the null vector as the solution. --Then, I tried to solve for a few unknowns at a time. I solved three equations for three unknowns: F2,x1, and x2. It worked for the first set of unknowns. But when I had to call those unknowns in the following equations, Mathematica told me that the variable did not exist. How can I call a particular variable from a solution vector to use in a following equation? If the solutions vector says, {F2-->20, x1-->2, x2-->3}, then why can I not type in F2 in the next equation as a defined variable? It would be much simpler if it was possible for me to just use Solve to find all 16 unknowns at the same time. Is that possible? URL: ,
