Index sets (IS)

IS objects are used to index into vectors and matrices and to set up vector scatters. Users guide section: Low-level Vector Communication.

Beginner - Basic usage

IS ISBlockSetIndices ISColoringType ISColoringValue ISCopy ISCreate ISCreateBlock ISCreateGeneral

ISCreateStride ISDestroy ISDuplicate ISGeneralFilter ISGeneralSetIndices ISGeneralSetIndicesFromMask ISGetLocalSize ISGetSize

ISGlobalToLocalMappingMode ISLOCALTOGLOBALMAPPINGBASIC ISLOCALTOGLOBALMAPPINGHASH ISLocalToGlobalMappingType ISShift ISStrideSetStride ISType PetscLayoutCompare

Intermediate - Setting options for algorithms and data structures
