NX Nastran DMAP Programmer's Guide - Kxcad.net

Parameters:
P2 Order of matrix.
P3 Skew flag. If nonzero, generate a skew-diagonal matrix.
P4 Precision (1 or 2). If zero, use machine precision.
Example:
Generate a real 10 x 10 identity matrix:
MATGEN ,/I10X10/1/10 $
Option P1 = 2
Generates an identity matrix trailer.
Format:
MATGEN ,/MAT/2/P2 $
Input Data Blocks:
None.
Output Data Block:
MAT Real identity matrix. See Remarks.
Parameters
P2 Order of matrix.
MATGEN
Matrix generator
This option differs from P1 = 1 in that only the trailer is generated (form = 8) and the
matrix is not actually generated. Only certain DMAP modules are prepared to accept
this form (e.g., MPYAD, FBS, CEAD). P1 = 1 is the preferred option.
Example:
Generate a real 10 x 10 identity matrix trailer:
MATGEN ,/TI10X10/2/10 $
Option P1 = 3
Generate a data block of prescribed size.
Format:
MATGEN ,/DB/3/P2 $
