oomph-lib: oomph::CompressedMatrixCoefficient Class Reference

Class for a compressed-matrix coefficent (for either CC or CR matrices). Contains the (row or column) index and value of a coefficient in a compressed row or column. Currently only used in ILU(0) for CCDoubleMatrices to allow the coefficients in each compressed column [row] to be sorted by their row [column] index. More...

Detailed Description

Class for a compressed-matrix coefficent (for either CC or CR matrices). Contains the (row or column) index and value of a coefficient in a compressed row or column. Currently only used in ILU(0) for CCDoubleMatrices to allow the coefficients in each compressed column [row] to be sorted by their row [column] index.
