HP32SII function?  Wolfgang K. Meister  01212009 hi all, besides my real HP32SII I have downloaded from http://freede.softonic.de/pocket/scalc.zip
a .swf file, compiled it with SWFKit to an .EXE The compiled version has two functions I do not understand:
1. 'm,b' called with a blue button
Both functions need x1,y1,x2,y2 as an argument.
Since I am not an expert  can someone please explain to me best regards
Wolfgang
Re: HP32SII function?  Walter B  01212009 I don't own such a SW calc, but I'd guess "m,b" returns the slope and intercept of a regression line. You may call m and b also a1 and a0 instead, since higher order regression curves will have more parameters.
No secure idea of the other button.
Re: HP32SII function?  bill platt  01212009 On the real HP 32sii, go to Rightshift L.R. [LN] and yo uwill see five softkeys:
xcarat ycarat r m b The x and y with carat over them are interpolate/extrapolations from linear regression, the r is the regression correlation, the m is the slope of the line (y/x) and b is the yintercept.
