double CV2D::getAbsMinComponent

(

void

)

const [inline]

Returns the value of the minimal point component.

int CV2D::getAbsMinComponentCoord

(

void

)

const

Returns the coordinate index of the minial point component (using fabs).

double CV2D::getMaxComponent

(

void

)

const [inline]

Returns the value of the maximal point component.

int CV2D::getMaxComponentCoord

(

void

)

const

Returns the coordinate index of the maximum point component.

double CV2D::getMinComponent

(

void

)

const [inline]

Returns the value of the minimal point component.

int CV2D::getMinComponentCoord

(

void

)

const

Returns the coordinate index of the minial point component.

double CV2D::getNorm

(

void

)

const [inline]

Returns the euclidian norm of the vector.

CV2D CV2D::getNormalized

(

void

)

const

Returns the normalized vector.

double CV2D::getX

(

void

)

const [inline]

Returns the x-coordinate of the vector.

double CV2D::getY

(

void

)

const [inline]

Returns the y-coordinate of the vector.

void CV2D::normalize

(

void

)

Normalizes the vector.

CV2D CV2D::operator *

(

double

)

const

Multiplication of a vector with a scalar.

double CV2D::operator *

(

const CV2D &

)

const

Scalar multiplication of two vectors. The result will be returned.

CV2D & CV2D::operator *=

(

double

)

Multiplies a vector with a scalar.

CV2D::operator CV3D

(

)

const

Cast operator to convert CV2D vectors to CV3D vectors. Initializes the new vector with this vector. The third component is set to 0.

bool CV2D::operator!=

(

const CV2D &

)

const

Compares to vectors. Same as above. Only the result is negated.

See also:

operator==()

CV2D CV2D::operator+

(

const CV2D &

)

const

Adds two vectors. The sum will be returned.

CV2D & CV2D::operator+=

(

const CV2D &

)

Adds another vector to this vector.

CV2D CV2D::operator-

(

void

)

const

Negates the vector.

CV2D CV2D::operator-

(

const CV2D &

)

const

Subtracts two vectors. The difference will be returned.

CV2D & CV2D::operator-=

(

const CV2D &

)

Subtracts another vector from this vector.

CV2D CV2D::operator/

(

double

)

const

Division of a vector with a scalar.

CV2D & CV2D::operator/=

(

double

)

Multiplies a vector with a scalar.

const CV2D & CV2D::operator=

(

const CV2D &

)

[inline]

Assign one vector to another.

bool CV2D::operator==

(

const CV2D &

)

const

Compares to vectors. The result will be 'true' if the two vector are indentically in each coefficient. Otherwise 'false' will be returned.

double CV2D::operator[]

(

int

i

)

const [inline]

Same as above but for constant vectors.

double& CV2D::operator[]

(

int

i

)

[inline]

Returns the i-th coefficient or the vector. The index goes from 0 to 3, so 0 stands for the x-coordinate, 1 for the y-coordinate and so on.

void CV2D::print

(

void

)

const

Prints a vector to the standard output.

void CV2D::setCoord	(	double	rdX,
		double	rdY
	)			[inline]

Set the value of the vector. The value of the vector will be (rdX, rdY, rdZ, rdW).

void CV2D::setX

(

double

rdX

)

[inline]

Sets the x-coordinate of the vector to 'x'.

void CV2D::setY

(

double

rdY

)

[inline]

Sets the y-coordinate of the vector to 'y'.
