UTRIV

       SUBROUTINE  UTRIV (V1,V,V2, NV,INCV)
 C$    (Incremental Vector)
 C$    For some  of  the  fitting routines,  it  is  necessary  to
 C$    generate vectors  containing equally-spaced  points.   This
 C$    routine provides this facility.  The arguments are:
 C$
 C$    (V1,V2)........Range of values to be placed in V(*).
 C$    V(*)...........Vector returned.
 C$    NV.............Number of  values  to  be  placed  in  V(*).
 C$                   These are V1, V1+DV, V1+2*DV, ..., V2, where
 C$                   DV = (V2-V1)/FLOAT(NV-1).
 C$    INCV...........Increment   between    successive    storage
 C$                   locations in V(*) (usually  1).  If INCV  is
 C$                   negative,  it  is  assumed  that  the   I-th
 C$                   element of the array is stored at location 1
 C$                   + (NV - I)*IABS(INCV), as is assumed in  the
 C$                   BLAS.
