+### Usage
+
+```c
+#include "stdlib/blas/ext/base/ndarray/cindex_of.h"
+```
+
+#### stdlib_blas_ext_cindex_of( arrays )
+
+Returns the first index of a search element in a one-dimensional single-precision complex floating-point ndarray.
+
+```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 "stdlib/blas/base/shared.h"
+#include
+
+// Create an input ndarray:
+const float data[] = { 1.0f, 2.0f, 3.0f, 4.0f, 5.0f, 6.0f };
+int64_t shape[] = { 3 };
+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 );
+
+// Create zero-dimensional ndarrays containing the search element and the index from which to begin searching:
+const float sdata[] = { 3.0f, 4.0f };
+const int32_t fdata[] = { 0 };
+int64_t sstrides[] = { 0 };
+
+struct ndarray *searchElement = stdlib_ndarray_allocate( STDLIB_NDARRAY_COMPLEX64, (uint8_t *)sdata, 0, NULL, sstrides, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 1, submodes );
+struct ndarray *fromIndex = stdlib_ndarray_allocate( STDLIB_NDARRAY_INT32, (uint8_t *)fdata, 0, NULL, sstrides, 0, STDLIB_NDARRAY_ROW_MAJOR, STDLIB_NDARRAY_INDEX_ERROR, 1, submodes );
+
+// Resolve the index:
+const struct ndarray *arrays[] = { x, searchElement, fromIndex };
+CBLAS_INT idx = stdlib_blas_ext_cindex_of( arrays );
+// returns 1
+
+// Free allocated memory:
+stdlib_ndarray_free( x );
+stdlib_ndarray_free( searchElement );
+stdlib_ndarray_free( fromIndex );
+```
+
+The function accepts the following arguments:
+
+- **arrays**: `[in] struct ndarray**` list containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a zero-dimensional ndarray containing the search element.
+ - a zero-dimensional ndarray containing the index from which to begin searching.
+
+```c
+CBLAS_INT stdlib_blas_ext_cindex_of( const struct ndarray *arrays[] );
+```
+
+
+
+
+
+
+
+
+
+- The zero-dimensional ndarray containing the index from which to begin searching must have an `int32` data type.
