Example:
Build new BGPDT table based on the deformed state.
$ Convert displacement vector to basic
$ coordinate system
PARAML CSTM//’PRESENCE’////S,N,NOCSTM
IF (NOCSTM > -1) THEN $
MATMOD CSTM,SIL,BGPDT,,,/TRANS,/5//-1 $
MPYAD TRANS,UG/UGBASIC $
ELSE $
EQUIVX UG/UGBASIC/ALWAYS $
ENDIF $
$ Form vector containing new grid locations in
$ basic coordinate system

Parameters:
MATMOD
Matrix modification
I1, I2, I3 Matrices to search for simultaneous null columns. (Real or complex).
O1 Column vector which has 1.0 at those rows where all matrices selected
for searching have null columns.
O2 Square symmetric matrix which has 1.0 on the diagonal of those
columns where all matrices selected for searching have null columns.
NONULL Output-integer. Set to -1 if no simultaneous null columns found;
otherwise, it is set to the number of simultaneous null columns.
NMATRIX Input-integer-default=0. Number of matrices to be included in null
column search.
