+### Usage
+
+```c
+#include "stdlib/blas/ext/base/ndarray/striu2tril.h"
+```
+
+#### stdlib_blas_ext_striu2tril( arrays )
+
+Reflects the upper triangular part of a single-precision floating-point matrix `A` into the lower triangular part of another matrix `B`.
+
+```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
+
+// Create an ndarray for A:
+float dataA[] = { 1.0f, 2.0f, 3.0f, 4.0f };
+int64_t shape[] = { 2, 2 };
+int64_t stridesA[] = { 2 * STDLIB_NDARRAY_FLOAT32_BYTES_PER_ELEMENT, STDLIB_NDARRAY_FLOAT32_BYTES_PER_ELEMENT };
+int8_t submodes[] = { STDLIB_NDARRAY_INDEX_ERROR, STDLIB_NDARRAY_INDEX_ERROR };
+
+struct ndarray *A = stdlib_ndarray_allocate( STDLIB_NDARRAY_FLOAT32, (uint8_t *)dataA, 2, shape, stridesA, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 2, submodes );
+
+// Create an ndarray for B:
+float dataB[] = { 0.0f, 0.0f, 0.0f, 0.0f };
+int64_t stridesB[] = { 2 * STDLIB_NDARRAY_FLOAT32_BYTES_PER_ELEMENT, STDLIB_NDARRAY_FLOAT32_BYTES_PER_ELEMENT };
+
+struct ndarray *B = stdlib_ndarray_allocate( STDLIB_NDARRAY_FLOAT32, (uint8_t *)dataB, 2, shape, stridesB, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 2, submodes );
+
+// Create an ndarray for k:
+int32_t dataK[] = { 0 };
+int64_t stridesK[] = { 0 };
+int8_t submodesK[] = { STDLIB_NDARRAY_INDEX_ERROR };
+
+struct ndarray *k = stdlib_ndarray_allocate( STDLIB_NDARRAY_INT32, (uint8_t *)dataK, 0, NULL, stridesK, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 1, submodesK );
+
+// Perform computation:
+const struct ndarray *arrays[] = { A, B, k };
+stdlib_blas_ext_striu2tril( arrays );
+
+// Free allocated memory:
+stdlib_ndarray_free( A );
+stdlib_ndarray_free( B );
+stdlib_ndarray_free( k );
+```
+
+The function accepts the following arguments:
+
+- **arrays**: `[in] struct ndarray**` list containing the following ndarrays:
+
+ - `[in] struct ndarray*` a two-dimensional input ndarray corresponding to `A`.
+ - `[inout] struct ndarray*` a two-dimensional output ndarray corresponding to `B`.
+ - `[in] struct ndarray*` a zero-dimensional ndarray specifying the diagonal below which to ignore.
+
+```c
+void stdlib_blas_ext_striu2tril( const struct ndarray *arrays[] );
