+### Usage
+
+```c
+#include "stdlib/blas/base/sscal.h"
+```
+
+#### c_sscal( N, alpha, \*X, stride )
+
+Multiplies each element of a single-precision floating-point vector by a constant.
+
+```c
+float x[] = { 1.0f, 2.0f, 3.0f, 4.0f };
+
+c_sscal( 4, 5.0f, x, 1 );
+```
+
+The function accepts the following arguments:
+
+-   **N**: `[in] CBLAS_INT` number of indexed elements.
+-   **alpha**: `[in] float` scalar constant.
+-   **X**: `[inout] float*` input array.
+-   **stride**: `[in] CBLAS_INT` index increment for `X`.
+
+```c
+void c_sscal( const CBLAS_INT N, const float alpha, float *X, const CBLAS_INT stride );
+```
+
+#### c_sscal_ndarray( N, alpha, \*X, stride, offset )
+
+Multiplies each element of a single-precision floating-point vector by a constant using alternative indexing semantics.
+
+```c
+float x[] = { 1.0f, 2.0f, 3.0f, 4.0f };
+
+c_sscal_ndarray( 4, 5.0f, x, 1, 0 );
+```
+
+The function accepts the following arguments:

+-   **N**: `[in] CBLAS_INT` number of indexed elements.
+-   **alpha**: `[in] float` scalar constant.
+-   **X**: `[inout] float*` input array.
+-   **stride**: `[in] CBLAS_INT` index increment for `X`.
+-   **offset**: `[in] CBLAS_INT` starting index for `X`.

+void c_sscal_ndarray( const CBLAS_INT N, const float alpha, float *X, const CBLAS_INT stride, const CBLAS_INT offset );
