Detailed Description

Generic interface for matrix data types

Member Function Documentation

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

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

Implemented in SparseMatrix< T >, Matrix< T >, SymmetricMatrix< T >, and SymmetricSparseMatrix< T >.

void Resize	(	int	num_rows,
		int	num_cols
	)

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

Implemented in Matrix< T >, SparseMatrix< T >, and SymmetricMatrix< T >.

IMatrix<T> Transpose

(

)

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

Returns

the transpose of the matrix (copy)

Implemented in SparseMatrix< T >, Matrix< T >, and SymmetricMatrix< T >.

Property Documentation

bool IsSymmetric

get

True if the matrix is stored in a symmetric manner, false otherwise

Also true for skew symmetric matrices that exploit this property in order to save memory

int NumberOfColumns

get

The number of columns of the matrix

The number of columns of the matrix

int NumberOfRows

get

The number of rows of the matrix

The number of rows of the matrix

T this[int x, int y]

getset

The value at (i,j)

The value at (i,j)

Parameters

x	the row ID
y	the column ID
