RE: HP71B Enhanced Math LEX
I just released the latest revision (2b5) of the Math Pac 2 with the longawaited complex DET function. This function was one of main missing features of the original Math Pac, together with the missing complex inverse trig/hyper functions.
This release also includes a nice little feature suggested by Valentin Albillo to reduce the number of keystrokes when using the INTEGRAL and FNROOT functions. Now, instead of typing (for instance) INTEGRAL(0,1,E,IVAR^3IVAR^2+IVAR+2) you can just type: INTEG(0,1,E,IX^3IX^2+IX+2) With these additions, the Math Pac 2 reaches the BETA stage, meaning that I will no more add features and will wait for more tests and possible feedbacks before promoting it to the final 2B version. It's not the end of the Math Pac 2 project, I already have several ideas for future enhancements and it is (very) possible that there will be a version 2C later, but it will not be before several months because I have other projects to complete first. Also Valentin made several proposals that go well beyond my initial project goals, they may be part of an "Advanced Math Pac" later on. The Manual Supplement for the Math Pac 2B is available here.
