Method Details

value

public double value(double leftEdge,
 double rightEdge,
 double x)
             throws MathIllegalArgumentException

Compute the value of the smoothstep function for the given edges and argument.

Note that right edge is expected to be greater than left edge. It will throw an exception otherwise.

Overrides:

value in class SmoothStepFactory.SmoothStepFunction

Parameters:

leftEdge - left edge

rightEdge - right edge

x - Argument for which the function value should be computed

Returns:

the value of the polynomial at the given point

Throws:

MathIllegalArgumentException - if right edge is greater than left edge

value

public double value(double xNormalized)

Compute the value of the quadratic smoothstep for the given argument normalized between edges.

Specified by:

value in interface UnivariateFunction

Overrides:

value in class SmoothStepFactory.SmoothStepFunction

Parameters:

xNormalized - Normalized argument for which the function value should be computed. It is expected to be between [0:1] and will throw an exception otherwise.

Returns:

the value of the polynomial at the given point.
