MATMOD
Matrix modification
external sequence, and the IFO entry on the generated DMIG entry is set to 1 or 6.
If the form is 6 only the terms in one triangle are output. If the input matrix form
is 2 (rectangular form) the columns are labeled sequentially, starting with unity.
The IFO is set to 9. If the form is not 1, 2, or 6, the module returns with no output.
2. EQEXIN table must not be purged.
Example:
Output KGG and PG matrices in MATPOOL formatted table and punch to DMIG
Bulk Data entries (MATGEN Option 9 is being used to resequence them from internal
to external sort).
MATGEN EQEXIN/INTEXT/9/0/LUSET $
MPYAD INTEXT,KGG,/KGGE/1 $
MPYAD KGGE,INTEXT,/KGGEXT $
MATMOD KGGEXT,EQEXIN,,,,/MATPOOL1,/16/1 $
MPYAD INTEXT,PG,/PGEXT/1 $
MATMOD PGEXT,EQEXIN,,,,/MATPOOL2,/16/1 $
Option P1 = 17
Generate a g-size partitioning vector from a user-defined set of grid and/or scalar
points or from a user-supplied bit position that designates one of the USET sets.
Format:
MATMOD EQEXIN,USET,SIL,CASECC,,/CP/17/UBIT/SETFLG/
S,N,NOCP////////SETSTR1/SETSTR2/SETSTR3/SETSTR4 $
Input Data Blocks:
EQEXIN Equivalence table between external and internal grid/scalar
identification numbers.
USET Degree-of-freedom set membership table for g-set.
SIL Scalar index list.
CASECC Table of Case Control command images.
Output Data Block:
CP Column partitioning vector.
