Detailed Description

a skew symmetric (anti-symmetric) sparse matrix; consumes less memory

Constructor & Destructor Documentation

SkewSymmetricSparseMatrix ( int  dimension )

inline

Create a skew symmetric sparse matrix with a given dimension

Parameters

dimension

the dimension (number of rows/columns)

Member Function Documentation

override IMatrix<float> CreateMatrix ( int  num_rows, int  num_columns  )

inlinevirtual

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

Reimplemented from SymmetricSparseMatrix< T >.

virtual void Resize ( int  size )

inlinevirtualinherited

Resize to the given size

Parameters

size

the size

Reimplemented in SymmetricCorrelationMatrix.

void Resize ( int  num_rows, int  num_cols  )

inlineinherited

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 >.

SparseMatrix ( int  num_rows, int  num_cols  )

inlineinherited

Create a sparse matrix with a given number of rows

Parameters

num_rows	the number of rows
num_cols	the number of columns

SymmetricSparseMatrix ( int  dimension )

inlineinherited

Create a symmetric sparse matrix with a given dimension

Parameters

dimension

the dimension (number of rows/columns)

virtual IMatrix<T> Transpose ( )

inlinevirtualinherited

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 >.

Property Documentation

override bool IsSymmetric

get

Only true if all entries are zero, except for the diagonal

override float this[int x, int y]

getset

Access the elements of the sparse matrix

Parameters

x	the row ID
y	the column ID

Dictionary<int, T> this[int x]

getinherited

Get a row of the matrix

Parameters

x	the row ID
