I'm trying to put an s-curve into a buffer~ to use as a lookup table,
but I can't figure out the damn math. I gather the formula to use
would be: y= 1./ 1 + exp((b*x) -a)
b being a curve constant, & a shifting it. I was trying to peek into
a buffer using [expr 1. / 1. + exp(($f1*$f2) - $f3)] my curve
rockets up, but never levels out at the top.
Can someone who understands math tell me what I'm doing wrong?
Thank you o wise math people.
