Detailed Description

template<class T>
class meta::util::dense_matrix< T >

Simple wrapper class for representing a dense matrix laid out in row-major order (that is, its internal representation is a linear array of the rows).

Constructor & Destructor Documentation

template<class T >

meta::util::dense_matrix< T >::dense_matrix	(	uint64_t	rows,
		uint64_t	columns
	)

Constructs a dense_matrix with the specified number of rows and columns.

Construction of the matrix value-initializes all elements (just as std::vector does), which ensures that elements are set to 0 when T is a numeric type.

Parameters

rows	The desired number of rows
columns	The desired number of columns

Member Function Documentation

template<class T >

void meta::util::dense_matrix< T >::resize	(	uint64_t	rows,
		uint64_t	columns
	)

Resizes the dense_matrix to have the specified number of rows and columns.

All elements are reset to be value initialized, not just new ones!

Parameters

rows	The desired new number of rows
columns	The desired number of columns

template<class T >

T & meta::util::dense_matrix< T >::operator()	(	uint64_t	row,
		uint64_t	column
	)

Obtains the column-th element of the row-th row.

Parameters

row	The row index
column	The column index

Returns

a reference to the element at that position

template<class T >

const T & meta::util::dense_matrix< T >::operator()	(	uint64_t	row,
		uint64_t	column
	)		const

Obtains the column-th element of the row-th row.

Parameters

row	The row index
column	The column index

Returns

a const reference to the element at that position

template<class T >

auto meta::util::dense_matrix< T >::begin

(

uint64_t

row

)

Parameters

row	The row index

Returns

an iterator over the row-th row

template<class T >

auto meta::util::dense_matrix< T >::begin

(

uint64_t

row

)

const

Parameters

row	The row index

Returns

a const iterator over the row-th row

template<class T >

auto meta::util::dense_matrix< T >::end

(

uint64_t

row

)

Parameters

row	The row index

Returns

an iterator to the end of the row-th row

template<class T >

auto meta::util::dense_matrix< T >::end

(

uint64_t

row

)

const

Parameters

row	The row index

Returns

an iterator to the end of the row-th row

template<class T >

uint64_t meta::util::dense_matrix< T >::rows

(

)

const

Returns

the number of rows in the matrix

template<class T >

uint64_t meta::util::dense_matrix< T >::columns

(

)

const

Returns

the number of columns in the matrix
