Equation Solver and custom equation catalogue

[Giancarlo]

Hello,
Made some test on a equation library some times ago with Larsf. It has been a good programming exercise since we customised the solver application:

Equation library for the HP Prime

The variable declation is an issue only the first time you use the equation, then the variables remaines stored into the calc for future use. Since variables are visible only in the user variable list, it doesn't bother me too much if i don't clean the environment as i had to do with my hp48.

Hope it help

Giancarlo
