Interface representing correlation and similarity matrices
void AddEntity | ( | int | entity_id | ) |
Add an entity to the ICorrelationMatrix by growing it to the requested size.
Note that you still have to correctly compute and set the entity's correlation values
entity_id | the numerical ID of the entity |
Implemented in SymmetricCorrelationMatrix, and AsymmetricCorrelationMatrix.
|
inherited |
Create a matrix with a given number of rows and columns
num_rows | the number of rows |
num_columns | the number of columns |
Implemented in SparseMatrix< T >, SparseMatrix-g< float >, Matrix< T >, Matrix-g< float >, SparseBooleanMatrix, SkewSymmetricSparseMatrix, SymmetricMatrix< T >, SymmetricSparseMatrix< T >, SymmetricSparseMatrix-g< float >, and SymmetricSparseMatrix-g< int >.
void Resize | ( | int | size | ) |
Resize to the given size
size | the size |
Implemented in AsymmetricCorrelationMatrix, and SymmetricCorrelationMatrix.
|
inherited |
Grows or shrinks the matrix to the requested size, if necessary
The new entries are filled with zeros. Obsolete entries are removed.
num_rows | the number of rows |
num_cols | the number of columns |
Implemented in Matrix< T >, Matrix-g< float >, SparseBooleanMatrix, SparseMatrix< T >, SparseMatrix-g< float >, and SymmetricMatrix< T >.
|
inherited |
Get the transpose of the matrix, i.e. a matrix where rows and columns are interchanged
Implemented in SparseBooleanMatrix, SparseMatrix< T >, SparseMatrix-g< float >, Matrix< T >, Matrix-g< float >, and SymmetricMatrix< T >.
void Write | ( | StreamWriter | writer | ) |
Write out the correlations to a StreamWriter
writer | A StreamWriter |
Implemented in AsymmetricCorrelationMatrix, and SymmetricCorrelationMatrix.
|
getinherited |
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
|
getinherited |
The number of columns of the matrix
The number of columns of the matrix
|
getinherited |
The number of rows of the matrix
The number of rows of the matrix
|
get |
size of the matrix (number of entities)
|
getsetinherited |
The value at (i,j)
The value at (i,j)
x | the row ID |
y | the column ID |
