I was wondering if there is a simple formula to change an S-curve to have a flat area in the middle.
I am using the formula..
Where $B$ is the steepness of the curve.
This gives me a normal S-curve.
BUT i also want a curve to go up to a flat area then continue to go up. Eg..
I am not sure if this is still called a S-Curve but i am unsure of what to google.
