Wow. Nobody can say you aren't ambitious!
Okay, fine. I have no idea how to do the display stuff, though overline sounds good for vectors and matrices. Sounds like we need commands RVAR and MVAR that set a variable to be real or matrix respectively? (Hopefully they work on lists.) Do we need a separate vector type? Do we need to distinguish between row and column vectors? Claudio L. Wrote:Second digit (optional additional knowledge about the variable, these are bits): While this makes good sense for reals, the first two make no sense for complex numbers. For those, it makes more sense to specify the quadrant, but I suppose you could just do the sign of the real part, which would be better than nothing. I sortof used the CAS to simplify Boolean expressions. What I actually did was use EVAL to simplify, then use A>L to convert the algebraic to a list, then strip out all exponents, then convert back to an algebraic. MUCH easier to do with RULEAPPLY, of course! What exactly does RULEMATCH do?
