hp 33s / 35s  solving simultaneous 2 variable linear equations with complex coefficients  Printable Version + HP Forums (https://archived.hpcalc.org/museumforum) + Forum: HP Museum Forums (https://archived.hpcalc.org/museumforum/forum1.html) + Forum: Old HP Forum Archives (https://archived.hpcalc.org/museumforum/forum2.html) + Thread: hp 33s / 35s  solving simultaneous 2 variable linear equations with complex coefficients (/thread143852.html) 
hp 33s / 35s  solving simultaneous 2 variable linear equations with complex coefficients  Smalle  11162008 Is there a program for the hp33s / 35s similar for solving simultaneous equations having two variables using complex number coefficients? The 33s manual provides a program for 3 variable with real coefficients, and suggests replacing specfic coefficients with 0s and 1s while using it to solve for 2 variables. That method is not very convenient, and it would be convenient to have some way to switch between solving for two variable or three variables; whether for real or complex. Palmer O. Hanson, Jr. in this forum has developed programs for solving 3 variable simultaneous equations with complex coefficients using the hp33s/35s. Are there similar programs for 2 variables as well.

Re: hp 33s / 35s  solving simultaneous 2 variable linear equations with complex coefficients  bill platt  11162008 Am I missing something, or what? Why can't you adjust the 3 variable to a 2 variable routine? It would seem conceptually to be a trivial task.
Re: hp 33s / 35s  solving simultaneous 2 variable linear equations with complex coefficients  Stefan Vorkoetter  11172008 My Matrix MultiTool for the HP 35s will handle systems of anywhere from 2 up to 18 linear equations, and it will work with complex coefficients.
