Left sided vector clip

SCLIPL/DCLIPL/ICLIPL

incx ≥ 0

x is stored forward in array x; that is,

 

xi is stored in x((i−1)⋅incx+1).

incx < 0

x is stored backward in array x; that

 

is, xi is stored in x((in)⋅incx+1).

Use incx = 1 if the vector x is stored contiguously in array x; that is, if xi is stored in x(i). Refer to “BLAS Indexing Conventions” in the introduction to this chapter.
