Methods

	Name	Description
	Add(DoubleCsrSparseMatrix, DoubleCsrSparseMatrix)	Compute the sum of two sparse matrices. Performs the operation C = A + B, where C[i,j] = A[i,j] + B[i,j].
	Add(DoubleCsrSparseMatrix, DoubleCsrSparseMatrix, Double)	Computes the some of a sparse matrix with the scalar multiple of another. Performs the operation C = A + betaB where C[i,j] = A[i,j] + betaB[i,j].
	Clone	Creates a deep copy of self.
	Divide	Divides a sparse matrix by a scalar.
	Equals(Object)	Equals function for Compressed Row (CSR) formatted sparse matrices. (Overrides SparseMatrixDataStorage, TypeEquals(Object).)
	Equals(DoubleCsrSparseMatrix)	Equals function for Compressed Row (CSR) formatted sparse matrices.
	GetHashCode	Gets the hash code for this instance. (Overrides SparseMatrixDataStorage, TypeGetHashCode.)
	Multiply(Double, DoubleCsrSparseMatrix)	Multiply a scalar and a sparse matrix.
	Multiply(DoubleCsrSparseMatrix, Double)	Multiply a scalar and a sparse matrix.
	Scale	Scales each element in the matrix by the specified value.
	Subtract	Subtracts two sparse matrices.
	ToCommaSeparated	Returns a formatted string representation of this matrix using commas and newlines. (Inherited from SparseMatrixDataStorage, Type.)
	ToCommaSeparated(String)	Returns a formatted string representation of this matrix using commas and newlines. Numbers are formatted using the specified format string. (Inherited from SparseMatrixDataStorage, Type.)
	ToDenseMatrix	Converts this sparse matrix to a dense matrix.
	ToString	Returns a formatted string representation of this matrix. (Inherited from SparseMatrixDataStorage, Type.)
	ToString(String)	Returns a formatted string representation of this matrix. Numbers are displayed using the specified format. (Inherited from SparseMatrixDataStorage, Type.)
	ToTabDelimited	Returns a formatted string representation of this matrix using tabs and newlines. (Inherited from SparseMatrixDataStorage, Type.)
	ToTabDelimited(String)	Returns a formatted string representation of this matrix using tabs and newlines. Numbers are formatted using the specified format string. (Inherited from SparseMatrixDataStorage, Type.)
	TransposeAdd(DoubleCsrSparseMatrix, DoubleCsrSparseMatrix)	Computes the sum of the transpose of one sparse matrix with another sparse matrix. Performs the operation C = A' + B, where ' denotes transpose and C[i,j] = A[j,i] + B[i,j].
	TransposeAdd(DoubleCsrSparseMatrix, DoubleCsrSparseMatrix, Double)	Computes the sum of the transpose of one sparse matrix with a scalar multiple another sparse matrix. Performs the operation C = A' + beta*B, where ' denotes transpose and C[i,j] = A[j,i] + B[i,j].
