Detailed Description

The default sparse matrix class.

It extends SparseMatrixBase. While SparseMatrixBase provides the storage scheme and assumes that the storage concerns a general matrix, SparseMatrix can define several modes for the storage type. The user can change these modes by setting a flag without changing the data (only the behaviour), these types are:

• general
• selfadjoint (symmetric), but all coefficients are stored
• selfadjoint, only lower triangular coefficients are stored
• selfadjoint, only upper triangular coefficients are stored. Depending on the type, algebraic operations will be applied.

Member Function Documentation

[Library]

returns unary minus (B=-A)

[Library]

overrides the sparsematrix-densevector product Dott (x'Ax).

overrides the sparsematrix-scalar product.

[Library]

overrides the sparsematrix-densematrix product. If the type of the sparse matrix is known (

See also:

matrixType()), then the product will be performed following the scheme.

overrides the sparsematrix-sparsematrix sum.

overrides the sparsematrix-sparsematrix subtraction

overrides the sparsematrix-scalar division.

prints the sparse matrix up to the given rows and columns (internally a temporary dense matrix will be created)
