The HP Advantage Pac module

The Advantage Pac Module adds several features not normally found on the HP41.

The most useful to me are:

• MATRX : Simple square matrix “Simultaneous Equation” solutions
• CFIT : Fitting data to various curves : LIN/LOG/E^x/Power
• SOLVE and INTEGrate : similar to the HP15C/DM15L functions
• TVM : Finance calculations

Also available are

• Complex Numbers
• Number Bases and Boolean Logic

These are better handled in the Angel Martin modules HP-41Z and HP-16C

• Vector
• Polynomial Solver
• Matrix (more extensive than the one above)
• Differential Equations
• Co-ordinate Transformations

These are less useful to me (at the moment)

Remember to Clear FLAG 21 after using any Advantage Pac programs - by turning the DM41X OFF and ON again….
