incx < 0

x is stored backward in array x; that

 

 

is, xi is stored in x((i−n)⋅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.

 

y

Array of length leny = (n−1)⋅incy+1 containing the

 

n-vector y.
