 -   **α**: scalar constant.
 -   **A**: input matrix stored in linear memory.
 -   **lda**: stride of the first dimension of `A` (a.k.a., leading dimension of the matrix `A`).
--   **x**: an `M` element input array.
+-   **x**: input array.
 -   **sx**: stride length for `x`.
 -   **β**: scalar constant.
--   **y**: an `N` element input array.
+-   **y**: output array.
 -   **sy**: stride length for `y`.
 
 The stride parameters determine how operations are performed. For example, to iterate over every other element in `x` and `y`,
