incx
incx is a parameter used in the Basic Linear Algebra Subprograms (BLAS) library to describe the storage stride between successive elements of a vector x. It controls how the elements of x are accessed during vector operations, enabling work on sub-vectors, strided data, or reversed sequences without copying data. The value of incx is an integer and is typically supplied along with a vector length and other parameters to BLAS routines.
In BLAS Level 1 routines such as dot product, axpy, and copy, incx specifies how far to
The corresponding parameter for the other vector in many routines is incy. Together with the length n,
Implementation and usage notes: incx must be a nonzero integer; a zero value would cause undefined behavior
While incx appears most often in BLAS contexts, it is generally a library-specific term rather than a
