Detailed Description

Class for storing dense matrices

The data is stored in row-major mode. Indexes are zero-based.

Template Parameters

T	the type of the matrix entries

Constructor & Destructor Documentation

Matrix	(	int	dim1,
		int	dim2
	)

inline

Initializes a new instance of the Matrix class

Parameters

dim1	the number of rows
dim2	the number of columns

Matrix	(	int	dim1,
		uint	dim2
	)

inline

Initializes a new instance of the Matrix class

Parameters

dim1	the number of rows
dim2	the number of columns

Matrix	(	uint	dim1,
		int	dim2
	)

inline

Initializes a new instance of the Matrix class

Parameters

dim1	the number of rows
dim2	the number of columns

Matrix	(	uint	dim1,
		uint	dim2
	)

inline

Initializes a new instance of the Matrix class

Parameters

dim1	the number of rows

Matrix ( Matrix< T > matrix )

inline

Copy constructor. Creates a deep copy of the given matrix.

Parameters

matrix the matrix to be copied

Matrix ( IList< IList< T >> data )

inline

Constructor that takes a list of lists to initialize the matrix

Parameters

data	a list of lists of T

Member Function Documentation

void AddRows ( int num_rows )

inline

Enlarges the matrix to num_rows rows

Do nothing if num_rows is less than dim1. The new entries are filled with zeros.

Parameters

num_rows the minimum number of rows

IMatrix<T> CreateMatrix	(	int	num_rows,
		int	num_columns
	)

inline

Create a matrix with a given number of rows and columns

Parameters

num_rows	the number of rows
num_columns	the number of columns

Returns: A matrix with num_rows rows and num_column columns

Implements IMatrix< T >.

IList<T> GetColumn ( int j )

inline

Returns a copy of the j-th column of the matrix

Parameters

j	the column ID

Returns: a list of T containing the column data

IList<T> GetRow ( int i )

inline

Returns a copy of the i-th row of the matrix

Parameters

i	the row ID

Returns: a list of T containing the row data

void Init ( T d )

inline

Init the matrix with a default value

Parameters

d	the default value

void Resize	(	int	num_rows,
		int	num_cols
	)

inline

Grows or shrinks the matrix to the requested size, if necessary

The new entries are filled with zeros. Obsolete entries are removed.

Parameters

num_rows	the number of rows
num_cols	the number of columns

Implements IMatrix< T >.

void SetColumn	(	int	j,
		IList< T >	column
	)

inline

Sets the values of the j-th column to the values in a given array

Parameters

j	the column ID
column	a list of T of length dim2

void SetColumnToOneValue	(	int	j,
		T	v
	)

inline

Sets an entire column to a specified value

Parameters

v	the value to be used
j	the column ID

void SetRow	(	int	i,
		IList< T >	row
	)

inline

Sets the values of the i-th row to the values in a given array

Parameters

i	the row ID
row	a list of T of length dim1

void SetRowToOneValue	(	int	i,
		T	v
	)

inline

Sets an entire row to a specified value

Parameters

v	the value to be used
i	the row ID

IMatrix<T> Transpose ( )

inline

Get the transpose of the matrix, i.e. a matrix where rows and columns are interchanged

Returns: the transpose of the matrix (copy)

Implements IMatrix< T >.
