DESCRIPTION

FlFSetTrapez realizes a trapezium shaped membership function on the base of an LR fuzzy set.

Constructors:

FlFSetTrapez()

FlFSetTrapez(FlParam *param);

FlFSetTrapez(double xm1, double xm2, double xalpha, double xbeta);

FlFSetTrapez(double min, double max, double xm1, double xm2, double xalpha, double xbeta);

FlFSetTrapez(FlStringR xname, double xm1, double xm2, double xalpha, double xbeta);

FlFSetTrapez(FlStringR xname, double min, double max, double xm1, double xm2,

double xalpha, double xbeta);

Initialize FlFSetTrapez with name as the object's name. xm1 is the x-value of the left maximum, xm2 of the right one. xalpha is the left and xbeta the right slope. min and max are the function's minimum / maximum.

virtual double get_membership(double x) const;

Returns the membership value for x.
