int ISGlobalToLocalMappingApply(ISLocalToGlobalMapping mapping, ISGlobalToLocalMappingType type, int n, int *idx,int *nout,int *idxout)Not collective
mapping | - mapping between local and global numbering |
type | - IS_GTOLM_MASK - replaces global indices with no local value with -1 IS_GTOLM_DROP - drops the indices with no local value from the output list |
n | - number of global indices to map |
idx | - global indices to map |
nout | - number of indices in output array (if type == IS_GTOLM_MASK then nout = n) |
idxout | - local index of each global index, one must pass in an array long enough to hold all the indices. You can call ISGlobalToLocalMappingApply() with idxout == PETSC_NULL to determine the required length (returned in nout) and then allocate the required space and call ISGlobalToLocalMappingApply() a second time to set the values. |
