+### Usage
+
+```c
+#include "stdlib/blas/ext/base/ndarray/czero_to.h"
+```
+
+#### stdlib_blas_ext_czero_to( arrays )
+
+Fills a one-dimensional single-precision complex floating-point ndarray with linearly spaced numeric elements which increment by `1` starting from zero.
+
+```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 <stdint.h>
+
+// Create an ndarray:
+float data[] = { 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f };
+int64_t shape[] = { 4 };
+int64_t strides[] = { STDLIB_NDARRAY_COMPLEX64_BYTES_PER_ELEMENT };
+int8_t submodes[] = { STDLIB_NDARRAY_INDEX_ERROR };
+
+struct ndarray *x = stdlib_ndarray_allocate( STDLIB_NDARRAY_COMPLEX64, (uint8_t *)data, 1, shape, strides, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 1, submodes );
+
+// Fill the ndarray:
+const struct ndarray *arrays[] = { x };
+stdlib_blas_ext_czero_to( arrays );
+
+// Free allocated memory:
+stdlib_ndarray_free( x );
+```
+
+The function accepts the following arguments:
+
+-   **arrays**: `[inout] struct ndarray**` list containing a one-dimensional input ndarray.
+
+```c
+void stdlib_blas_ext_czero_to( const struct ndarray *arrays[] );
+```
