|
||
|
|
C -- XN, YN, ZN - IN - the nodal coordinates
|
||
|
|
C -- COLMIN, ROWMIN - IN - the minimum column and row value and 1 / interval
|
||
|
|
C -- CRDELT - the column and row interval reciprical (1 / interval)
|
||
|
|
C -- NUMCOL, NUMROW - IN - the number of columns and rows
|

|
|
C -- IXNCRS, IXNCRE - OUT - the starting and ending NPCR index
|
||
|
|
C -- for each column and row
|
||
|
|
C -- NPCR - OUT - the nodes indexed by IXNCRS, IXNCRE
