MATXSH

       SUBROUTINE  MATXSH (OX,OY,OZ, SYFORX,SZFORX, SXFORY,SZFORY,
      X                   SXFORZ,SYFORZ)
 C$    (Transform -- Shear Matrix)
 C$    Construct a shear matrix.  The stored transformation matrix
 C$    is multiplied on  the right by  the computed shear  matrix.
 C$
 C$    The arguments are:
 C$
 C$    (OX,OY,OZ).....Coordinates of point about which shears are
 C$                   applied.
 C$    S*FOR*.........Shear parameters.  SYFORX = SHEAR in Y for
 C$                   unit increase in X, and similarly for the
 C$                   others.
 C$
 C$    MATXSM() sets  the  stored  matrix  to  a  starting  value,
 C$    MATXIM() inquires the current  value, and MATXIO()  selects
 C$    printing of intermediate matrices.
