All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

Braket

public class Vect

extends Argument

Class representing a mathematical vector. The string representation of the default vector is given by [a b c]. The default vector therefore is a dual vector. A normal vector is created by parsing [a b c]' or calling the constructor followed by a transpose() operation.

Braket

Field Summary

protected Complex[]	data holds the components.
int	dimension holds the dimension
protected boolean	transpose holds the information whether or not the vector is transposed.

Fields inherited from class edu.buffalo.fs7.mathlib.MathObject

Constructor Summary

Vect()
generates a vector of dimension 0.

Vect(int dimension)
generates a 0-vector of dimension dimension

Vect(MathObject o)
clone constructor.

Method Summary

java.lang.Object	clone() clones the vector.
void	conjugate() conjugates the vector
boolean	equals(MathObject o) equality predicate
Complex	getElement(int x) returns the component of the vector specified by x.
void	negative() negates the vector
static Vect	parseVector(java.lang.String str) parses the vect object from a string.
java.lang.String	toParseableString() returns a parseable representation of the object
java.lang.String	toString() returns a string representation of the object (not necessarily parseable).
void	transpose() transposes the vector

Field Detail

data

protected Complex[] data

holds the components. Should not be accessed directly, but via the getElement() method.

See Also:

getElement(int)

transpose

protected boolean transpose

holds the information whether or not the vector is transposed.

dimension

public int dimension

holds the dimension

Constructor Detail

Vect

public Vect()

generates a vector of dimension 0.

Vect

public Vect(int dimension)

generates a 0-vector of dimension dimension

Parameters:

dimension - the dimension of the vector

Vect

public Vect(MathObject o)

clone constructor. If the object given as a parameter is another vect object, a new vector with the same properties is generated.

Method Detail

clone

public java.lang.Object clone()

clones the vector.

Overrides:

clone in class MathObject

Vect(MathObject)

parseVector

public static Vect parseVector(java.lang.String str)
                        throws java.lang.NumberFormatException,
                               java.lang.IllegalArgumentException

parses the vect object from a string. Throws NumberFormatException or IllegalArgumentException if parsing failed.

Parameters:

str - string of the form [a b c]

Returns:

a Vect object corresponding to the vector described by the string

transpose

public void transpose()

transposes the vector

conjugate

public void conjugate()

conjugates the vector

negative

public void negative()

negates the vector

equals

public boolean equals(MathObject o)

equality predicate

Overrides:

equals in class Argument

Returns:

true if the MathObject o is equal to this vector

getElement

public Complex getElement(int x)

returns the component of the vector specified by x.

Parameters:

x - number of component starting with 0

Returns:

complex component

toString

public java.lang.String toString()

Description copied from class: MathObject

returns a string representation of the object (not necessarily parseable).

Overrides:

toString in class MathObject

Returns:

string representation of the vector object

toParseableString

public java.lang.String toParseableString()

Description copied from class: MathObject

returns a parseable representation of the object

Overrides:

toParseableString in class MathObject

Returns:

parsable string representation of ths vector object.
