The bounding functions, with their inverses and derivatives.

Usage

1
ndfboundp(x, minb, maxb, hbf)

Arguments

x

The input value.

minb

The minimum bound.

maxb

The maximum bound.

hbf

The hybrid bounded flag. Determines which function is used.

Details

If hbf=0 then the function is minb+(maxb-minb)/(1+exp(-x)), otherwise it is minb+(maxb-minb)*(.5*sin(x*pi/2)+.5).

Value

Numeric function value.
