Solving simultaneous equations involving complex numbers

[Helge Gabert]

If you put that in the bucket of requests, please take the time to look at the SOLVESYS library for the Hp48/49/50 series on hpcalc.org. SOLVESYS is very fast, has a well-organized menu and works with simultaneous linear and non-linear systems of equations. Complex coefficents are allowed, and complex solutions are, too (check on/off). The user can also indicate which variables to solve for, and which should remain symbolic. The diagnostics are extensive, and useful. The SOLVESYS interface would be a wonderful replacement for the SOLVE app.

I use SOLVESYS when I need to do *real* work, and it hasn't failed me yet.
