Member Function Documentation

composeWith()

Fper etvo::Fper::composeWith

(

const Fper &

f

)

const

Computes the composition of *this with f.

Parameters

f	an Fper object

an Fper object

getCodomPer()

int etvo::Fper::getCodomPer

(

)

const

returns the codomain period codP

getDomPer()

int etvo::Fper::getDomPer

(

)

const

returns the domain period dP

getValue()

int etvo::Fper::getValue

(

int

arg

)

const

Value of f(x)

Parameters

arg

x

Returns

f(x)

getyMax0()

double etvo::Fper::getyMax0

(

)

const

gives the maximum of f(x) projected on y axis [x=0] parallel to (dP,codP) line This value is important for improving max,min computation between functions

getyMin0()

double etvo::Fper::getyMin0

(

)

const

gives the minimum of f(x) projected on y axis [x=0] parallel to (dP,codP) line This value is important for improving max,min computation between functions

operator()()

int etvo::Fper::operator()

(

int

arg

)

const

Value of f(x)

Parameters

arg

x

Returns

f(x)

setPeriodicity()

void etvo::Fper::setPeriodicity	(	int	dP,
		int	codP
	)

Set dP/codP.

Parameters

dP	domain period
codP	codomain period

setSeq()

void etvo::Fper::setSeq

(

const std::vector< int > &

seq

)

Set values of f(0),f(1), ... over one period.

Parameters

seq	: values of f(0),f(1),

toString()

std::string etvo::Fper::toString ( ) const

virtual

Returns a string description of a pseudo-periodic function Ex: "[-7 -7 -3 -3 ](4,5)" for a (4,5) pseudo-periodic function f(0)=-7,f(1)=-7,f(2)=-3 ...

Reimplemented in etvo::Fminp, and etvo::Fmaxp.
