Index sets (IS)

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

Beginner - Basic usage

IS ISBlockSetIndices ISColoringType 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
