Detailed Description

DoubleVector is of variable length, and contains double precision.

Constructor & Destructor Documentation

◆ DoubleVector() [1/2]

DoubleVector::DoubleVector ( int e )

inlineexplicit

Parameters

e	Default dimensions start at 1, end at e

◆ DoubleVector() [2/2]

DoubleVector::DoubleVector	(	int	s,
		int	e
	)

inline

Parameters

e	Dimensions start at s, end at e

Member Function Documentation

◆ average()

double DoubleVector::average ( ) const

Average element of the vector.

average element

◆ dot()

double DoubleVector::dot ( const DoubleVector & v ) const

inline

< dot product

◆ setEnd()

void DoubleVector::setEnd ( int e )

Changes the length of a vector - copies as many elements of old one as possible, and fills any extra up with zeroes
