Detailed Description

An encapsulation of a column Vector (that is a specialization of a Matrix for convenience).

Constructor & Destructor Documentation

Vector() [1/3]

Vector::Vector

(

)

Construct a 2x1 Vector.

Vector() [2/3]

Vector::Vector ( int  size )

explicit

Construct a size x 1 Vector.

Parameters

size	The number of rows

Vector() [3/3]

Vector::Vector

(

const Vector &

original

)

Copy constructor.

Parameters

original

The Vector to copy

Member Function Documentation

operator=() [1/2]

Vector & Vector::operator=

(

std::initializer_list< double >

m

)

Assign an initializer_list to this Vector.

Parameters

m	The initializer_list containing the values

Exceptions

length_error

if the list is the wrong size

Returns

The Vector referred to by this

operator=() [2/2]

Vector & Vector::operator=

(

const Matrix &

other

)

Assign an (appropriately sized) Matrix to this Vector.

Note: This method is not void so that one can write x = y = z (which first assigns z to y and then assigns the result of that assignment to x). It returns the result by reference because there is no concern that this will not refer to something.

Parameters

other

The Matrix to copy

Exceptions

length_error

if the sizes don't conform

Returns

The Vector referred to by this

Friends And Related Function Documentation

norm

double norm ( const Matrix &  a )

friend

Calculate the Euclidean norm of a Vector (really a 1-dimensional Matrix).

Parameters

a	The Vector

Returns

\( || \mathbf{a} || \)

normalized

Matrix normalized ( const Matrix &  a )

friend

Calculate the normalized version of a Vector (really a 1-dimensional Matrix).

Parameters

a	The Vector

Returns

\( \mathbf{a} / ||\mathbf{a}|| \)
