SyntaxThe DoubleSymCsrSparseMatrix type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | DoubleSymCsrSparseMatrix | Constructs an empty DoubleSymCsrSparseMatrix instance. |
| DoubleSymCsrSparseMatrix(CompressedSparseRowDouble) | Constructs a DoubleSymCsrSparseMatrix instance with the given data. Only the upper triangular part of the data will be referenced. |
| DoubleSymCsrSparseMatrix(IDictionaryIntPair, Double, Int32) | Constructs a DoubleSymCsrSparseMatrix instance from the given coordinate map format. Only the upper triangular, column greater than or equal to row, values will be referenced. |
Properties| Name | Description | |
|---|---|---|
 | Cols |
Gets the number of columns in the matrix.
(Inherited from SparseMatrixDataStorage, Type) |
| Data |
Gets and sets the formatted data for the matrix.
(Inherited from SparseMatrixDataStorage, Type) |
| Item |
Indexer for returning the element at the specified row and column.

Methods| Name | Description | |
|---|---|---|
 | Add(DoubleSymCsrSparseMatrix, DoubleSymCsrSparseMatrix) | Compute the sum of two symmetric sparse matrices. Performs the operation C = A + B, where C[i,j] = A[i,j] + B[i,j]. |
| Add(DoubleSymCsrSparseMatrix, DoubleSymCsrSparseMatrix, Double) | Computes the some of a symmetric sparse matrix with the scalar multiple of another. Performs the operation C = A + beta*B where C[i,j] = A[i,j] + beta*B[i,j]. |
| Clone |
Returns a deep copy of self.
(Overrides DoubleCsrSparseMatrixClone) |
| Equals(DoubleCsrSparseMatrix) |

| Equals(Object) |
Equals function for DoubleSymCsrSparseMatrix matrices.
(Overrides DoubleCsrSparseMatrixEquals(Object)) |
| GetHashCode |
Gets the hash code for this DoubleSymCsrSparseMatrix instance.
(Overrides DoubleCsrSparseMatrixGetHashCode) |
| Scale | Scales each element in the matrix by the specified value. |
 | ToCommaSeparated |
