Option P1 = 9
MATGEN
Matrix generator
Generate a transformation between external and internal sequence matrices for g-set
size matrices.
Format:
MATGEN EQEXIN/TRANS/9/P2/P3 $
Input Data Block:
EQEXIN Equivalence table between external and internal grid/scalar
identification numbers.
Output Data Block:
TRANS Transformation matrix.
Parameters:
T EQEXIN table output by module GP1.
P2 0 Output nontransposed factor where [UINT]=[MAT][UEXT].
Examples:
Transform a g-set size vector UGV to external sequence.
MATGEN EQEXIN/INTEXT/9//LUSET $
MPYAD INTEXT,UGV,/UGVEXT/1 $
Transform an a-set size matrix to external sequence.

MATGEN EQEXIN/INTEXT/9/0/LUSET $
SMPYAD INTEXT,KAGG,INTEXT,,/KAAGEXT/3////1////6 $
$ (KAAGEXT) = TRANSPOSE(INTEXT)*(KAAG)*
$ (INTEXT) ITS FORM IS 6 (SYMMETRIC)
By default in SOLs 1 through 200, PARAM, OLDSEQ is -1, which means this operation
is not required.
Option P1 = 10
Not used.
1 Output transposed factor where [UEXT]=[MAT][UINT]
P3 Number of terms in g-set. The parameter LUSET, which is output by the GP1
module, contains this number in most solution sequences.
