C --*** MUNXYZ *** (GJOIN) Compress coordinates from the second database

C -- Written by Amy Gilkey - revised 09/29/87
|
|
C --
|
|
C --MUNXYZ compresses the coordinates from the second database. The
|
|
C --coordinates that match the nodes in the first database are deleted
|
|
C --from the list.

C --
|
|
C --Parameters:
|
|
C -- NDIM - IN - the number of coordinates per node
|
|
C -- NUMNP2 - IN/OUT - the number of nodes in the second database;
|
|
C -- returned compressed
|
|
C -- NUMNP1 - IN - the number of nodes in the first database
|
|
C -- IXNP2 - IN/OUT - the index of the compressed node; if input as <0,
|
|
C -- there is no matching node and the new index is returned
|
|
C -- XN2, YN2, ZN2 - IN/OUT - the coordinates, returned compressed
