Method Detail

clone

public java.lang.Object clone()

Method for Cloneable interface -- provides a deep copy of the current set, EXCEPT the hedges.

Overrides:

clone in class FzyBeta

Returns:

Object the new FzyWeightedBeta cloned.

initializeMembership

public FzySet initializeMembership()

Description copied from class: FzySCurve

Initialize this set's membership using a sinusoid (logistical) function.

[ i..(VECMAX-1)]:

[ domain[i] <= lowInflexionPoint ] { membership[i] = 2.0 ∗ ((domain[i]-lowDomain) / domainValOfCompleteMembership)^2.0;}

[ (domain[i] > lowInflextionPoint) && (domain[i] < domainValOfCompleteMembership) ] { membership[i] = 1.0 - 2.0 ∗ ((domain[i]-lowDomain)/(domainValOfCompleteMembership-lowDomain))^2.0;}

[ domain[i] == domainValOfCompleteMembership ] { membership[i] = 1.0; }

[ (domain[i] > domainValOfCompleteMembership) && (domain[i] <= highInflextionPoint) ] { membership[i] = 1.0 - 2.0 ∗ ((domainValOfCompleteMembership-domain[i])/(highDomain-domainValOfCompleteMembership))^2.0;}

[ domain[i] > highInflexionPoint ] { membership[i] = 2.0 ∗ (highDomain-domain[i])/(highDomain-domainValOfCompleteMembership))^2.0;}

Overrides:

initializeMembership in class FzyBeta

Tags copied from class: FzySet

Returns:

FzySet the set.

Throws:

FzySystemException - if a computation exception occurs.

toString

public java.lang.String toString()

Used to provide a text description of this fuzzy set.

Overrides:

toString in class FzyBeta

typeAsString

public java.lang.String typeAsString()

Overrides:

typeAsString in class FzyBeta
