+
+```c
+#include "stdlib/blas/ext/base/ssorthp.h"
+```
+
+#### stdlib_strided_ssorthp( N, order, \*X, strideX )
+
+Sorts a single-precision floating-point strided array using heapsort.
+
+```c
+float x[] = { 1.0f, -2.0f, 3.0f, -4.0 };
+
+stdlib_strided_ssorthp( 2, -1.0f, x, 1 );
+```
+
+The function accepts the following arguments:
+
+-   **N**: `[in] CBLAS_INT` number of indexed elements.
+-   **order**: `[in] float` sort order. If `order < 0.0`, the input strided array `x` is sorted in **decreasing** order. If `order > 0.0`, the input strided array `x` is sorted in **increasing** order. If `order == 0.0`, the input strided arrays are left unchanged.
+-   **X**: `[inout] float*` input array.
+-   **strideX**: `[in] CBLAS_INT` stride length.
+
+```c
+stdlib_strided_ssorthp( const CBLAS_INT N, const float order, float *X, const CBLAS_INT strideX );
