Member Function Documentation

void IRIS::Fuzzy::Numeric::clear (   )

clears out a membership function Reimplemented in IRIS::Fuzzy::MembershipFn.

virtual void IRIS::Fuzzy::Numeric::discretize (  unsigned  degree  )  [pure virtual]

discretize a membership function based on the given degree of discretization (number of elements in the vectorized form) Parameters: degree  degree of discretization (or number of elements in the vectorized form of this membership function) Implemented in IRIS::Fuzzy::BellMF, IRIS::Fuzzy::dSigMF, IRIS::Fuzzy::GaussMF, IRIS::Fuzzy::MembershipFn, IRIS::Fuzzy::pSigMF, IRIS::Fuzzy::SigMF, IRIS::Fuzzy::TrapMF, IRIS::Fuzzy::TriMF, and IRIS::Fuzzy::ZMF.

void IRIS::Fuzzy::Numeric::draw (   )  const [virtual]

draw this set to see what it looks like; included primarily for debugging purposes ... Implements IRIS::Fuzzy::Set. Reimplemented in IRIS::Fuzzy::BellMF, IRIS::Fuzzy::dSigMF, IRIS::Fuzzy::GaussMF, IRIS::Fuzzy::MembershipFn, IRIS::Fuzzy::pSigMF, IRIS::Fuzzy::SigMF, IRIS::Fuzzy::TrapMF, IRIS::Fuzzy::TriMF, and IRIS::Fuzzy::ZMF.

virtual double IRIS::Fuzzy::Numeric::eval (  double  x  )  const [pure virtual]

evaluate a membership function based on the given x Parameters: x  element of domain of membership function Implemented in IRIS::Fuzzy::BellMF, IRIS::Fuzzy::dSigMF, IRIS::Fuzzy::GaussMF, IRIS::Fuzzy::MembershipFn, IRIS::Fuzzy::pSigMF, IRIS::Fuzzy::SigMF, IRIS::Fuzzy::TrapMF, IRIS::Fuzzy::TriMF, and IRIS::Fuzzy::ZMF.

void IRIS::Fuzzy::Set::get (  string &  name  )  const [inherited]

get the name of this set; same as getName() Parameters: name  name given this set See also: getName()

string IRIS::Fuzzy::Set::getName (   )  const [inherited]

get the name of this set

Numeric::vector IRIS::Fuzzy::Numeric::getVector (   )  const

gets the vectorized form of a membership function based on the set level of discretization

virtual double IRIS::Fuzzy::Numeric::operator() (  double  val  )  const [pure virtual]

evaluate membership of the given value in this set Parameters: val  value to use when evaluating this set Implemented in IRIS::Fuzzy::BellMF, IRIS::Fuzzy::dSigMF, IRIS::Fuzzy::GaussMF, IRIS::Fuzzy::MembershipFn, IRIS::Fuzzy::pSigMF, IRIS::Fuzzy::SigMF, IRIS::Fuzzy::TrapMF, IRIS::Fuzzy::TriMF, and IRIS::Fuzzy::ZMF.

double IRIS::Fuzzy::Numeric::operator[] (  unsigned  i  )  const

gets the ith item in the vector of the member function

double & IRIS::Fuzzy::Numeric::operator[] (  unsigned  i  )

sets the ith item in the vector of the member function

void IRIS::Fuzzy::Set::set (  const string &  name  )  [inherited]

set the name for this set; same as setName() Parameters: name  name to give this set See also: setName()

void IRIS::Fuzzy::Set::setName (  const string &  name  )  [inherited]

set the name for this set Parameters: name  name to give this set
