Solving Large Systems of Equations

[parisse]

What kind of system is it? For a linear system, the command is linsolve. For several linear systems with same matrix, it's lu + linsolve. Should work without problem with dozens of equations and variables on the calc.
For non linear systems, if the system is polynomial you can try solve. Otherwise you must use an iterative method, fsolve provides that.
If you get a strange error message, please send us the system.
