Solving simultaneous equations involving complex numbers

[mbeddo]

I was meeting with my department chair today, and he asked if there was a way to solve linear equations involving complex numbers using TI-84 calculators (these are ubiquitous at our college). There isn't - not without writing a program to do it.

After I got back home, I went through the user guide for the HP Prime. I'd like to advocate for the HP Prime among our students, but it seems neither the Solve or Linear Solver apps can handle complex numbers. So it seems a program is required there as well.

One has to solve such equations all the time in Circuit Analysis courses, where the impedance can be complex.

Am I missing something?
