Synopsis#
Values#
PC_DEFLATION_SPACE_HAAR- directly assembled based on Haar (db2) wavelet with overflowed filter cuted-offPC_DEFLATION_SPACE_DB2-MATCOMPOSITEof 1-lvl matices based on db2 (2 coefficient Daubechies / Haar wavelet)PC_DEFLATION_SPACE_DB4- same as above, but with db4 (4 coefficient Daubechies)PC_DEFLATION_SPACE_DB8- same as above, but with db8 (8 coefficient Daubechies)PC_DEFLATION_SPACE_DB16- same as above, but with db16 (16 coefficient Daubechies)PC_DEFLATION_SPACE_BIORTH22- same as above, but with biorthogonal 2.2 (6 coefficients)PC_DEFLATION_SPACE_MEYER- same as above, but with Meyer/FIR (62 coefficients)PC_DEFLATION_SPACE_AGGREGATION- aggregates local indices (given by operator matrix distribution) into a subdomainPC_DEFLATION_SPACE_USER- indicates space set by user
Note#
Wavelet-based space (except Haar) can be used in multilevel deflation.
