Detailed Description

template<typename T>
class Matrix2< T >

A simple 2D matrix class for linear algebra operations.

This class provides basic matrix operations including matrix-vector multiplication. It is implemented using std::vector of std::vector as the underlying storage.

Template Parameters

T	The element type (typically float or double)

Constructor & Destructor Documentation

Matrix2()

template<typename T >

Matrix2< T >::Matrix2 ( size_t  rows, size_t  cols  )

inline

Construct a matrix with specified dimensions.

Creates a matrix with the given number of rows and columns, initializing all elements to the default value of type T.

Parameters

[in]	rows	The number of rows in the Matrix2
[in]	cols	The number of columns in the Matrix2

Member Function Documentation

cols()

template<typename T >

size_t Matrix2< T >::cols ( ) const

inline

Returns the number of columns in the Matrix2.

Returns

The number of columns in the Matrix2.

operator*()

template<typename T >

Vector2< T > Matrix2< T >::operator* ( const Vector2< T > &  v ) const

inline

Multiplies the given Vector2 by the elements of this Matrix2.

\[ y_i = \sum_{j=1}^{n} A_{ij} x_j \]

Parameters

v	The Vector2 to multiply by the elements of this Matrix2.

Returns

The resulting Vector2 after the multiplication.

operator[]() [1/2]

template<typename T >

std::vector< T > & Matrix2< T >::operator[] ( size_t  i )

inline

Returns a reference to the vector of elements at the specified row index.

Parameters

i	The row index to access.

Returns

A reference to the vector of elements at the specified row index.

operator[]() [2/2]

template<typename T >

const std::vector< T > & Matrix2< T >::operator[] ( size_t  i ) const

inline

Returns a constant reference to the vector of elements at the specified row index.

Parameters

i	The row index to access.

Returns

A constant reference to the vector of elements at the specified row index.

rows()

template<typename T >

size_t Matrix2< T >::rows ( ) const

inline

Returns the number of rows in the Matrix2.

Returns

The number of rows in the Matrix2.
