+### Usage
+
+```c
+#include "stdlib/blas/ext/base/ndarray/sfill.h"
+```
+
+#### stdlib_blas_ext_sfill( arrays )
+
+Fills a one-dimensional single-precision floating-point ndarray with a specified scalar constant.
+
+```c
+#include "stdlib/ndarray/ctor.h"
+#include "stdlib/ndarray/dtypes.h"
+#include "stdlib/ndarray/index_modes.h"
+#include "stdlib/ndarray/orders.h"
+#include "stdlib/ndarray/base/bytes_per_element.h"
+#include
+#include
+
+// Create an ndarray:
+float dataX[] = { 1.0f, -2.0f, 3.0f, -4.0f };
+int64_t shape[] = { 4 };
+int64_t strides[] = { STDLIB_NDARRAY_FLOAT32_BYTES_PER_ELEMENT };
+int8_t submodes[] = { STDLIB_NDARRAY_INDEX_ERROR };
+
+struct ndarray *x = stdlib_ndarray_allocate( STDLIB_NDARRAY_FLOAT32, (uint8_t *)dataX, 1, shape, strides, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 1, submodes );
+
+// Create a zero-dimensional ndarray containing the scalar constant:
+float adata[] = { 5.0f };
+int64_t astrides[] = { 0 };
+
+struct ndarray *alpha = stdlib_ndarray_allocate( STDLIB_NDARRAY_FLOAT32, (uint8_t *)adata, 0, NULL, astrides, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 1, submodes );
+if ( x != NULL && alpha != NULL ) {
+ const struct ndarray *arrays[] = { x, alpha };
+ stdlib_blas_ext_sfill( arrays );
+}
+
+// Free allocated memory:
+stdlib_ndarray_free( x );
+stdlib_ndarray_free( alpha );
+```
+
+The function accepts the following arguments:
+
+- **arrays**: `[in] struct ndarray**` list containing the following ndarrays:
+
+ - `[inout] struct ndarray*` a one-dimensional input ndarray (pre-sliced to the desired range).
+ - `[in] struct ndarray*` a zero-dimensional ndarray containing the scalar constant to fill with.
+
+```c
+void stdlib_blas_ext_sfill( const struct ndarray *arrays[] );
