Hi. I would like to state first of all that I do know how to solve systems of equations in the complex domain by hand. But solving by hand is no longer required in my course, and getting the answers most quickly is becoming the highest priority. But the real problem is that I am getting into steady-state analysis and often have systems of equations from nodal or mesh analysis whereby the coefficients of a voltage or current are complex numbers. I would like to know two things: 1. Is there a simple way to solve such systems on a TI-89 calculator, presumably using matrices? Solving such systems is a cinch in the real domain using the "rref" function. 2. Is there a simple way to solve such systems in MatLab, presumably using matrices? If anyone could help, that would be great!
