Lines: 16 Originator: jacobsd@mist.CS.ORST.EDU On a number or my integration problems, an adaptive approach seems better than the plain iterative method that is standard with the 28S and 48SX. Why didn't HP use adaptive integration? I suppose it could be ROM space, but they don't seem that large. Any clues? I wrote an adaptive Gaussian Quadrature program for the 28S and will write it for the 48SX when I get mine (tomorrow). Has anyone else done any work with this? I'd like some information on writing it in a faster language (CHIP48? Machine?) also. I'll post the program if there's interest.
