SCLIP/DCLIP/ICLIP Two sided vector clip
x Array of length lenx = (n−1)×|incx|+1 containing the
n-vector x.
incx Increment for the array x:
incx ≥ 0 x is stored forward in array x; that is,
x
i
is stored in x((i−1)×incx+1).
incx < 0 x is stored backward in array x; that
is, x
i
is stored in x((i−n)×incx+1).
Use incx = 1 if the vector x is stored contiguously in
array x; that is, if x
i
is stored in x(i). Refer to “BLAS
Indexing Conventions” in the introduction to this
chapter.
