Input

n

Number of elements of vector x to be compared to a. If

 

 

n ≤ 0, the subprograms do not reference x.

 

x

Array of length lenx = (n−1)⋅incx+1 containing the

 

 

n-vector x.

 

incx

Increment for the array x. x is stored forward in array x

 

 

with increment incx; that is, xi is stored in

 

 

x((i−1)⋅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.
