+
+## Usage
+
+```javascript
+var zany = require( '@stdlib/blas/ext/base/ndarray/zany' );
+```
+
+#### zany( arrays )
+
+Tests whether at least one element in a one-dimensional double-precision complex floating-point ndarray is truthy.
+
+```javascript
+var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
+
+var x = new Complex128Vector( [ 0.0, 0.0, 1.0, 2.0 ] );
+
+var v = zany( [ x ] );
+// returns true
+```
+
+The function has the following parameters:
+
+-   **arrays**: array-like object containing a one-dimensional input ndarray.
+
+</section>
+
+<!-- /.usage -->
+
+<section class="notes">
+
+## Notes
+
+-   A complex number is truthy when at least one of its real or imaginary components is truthy.
+-   If provided an empty one-dimensional ndarray, the function returns `false`.
+-   The function explicitly treats `NaN` values as falsy.
+
+</section>
+
+<!-- /.notes -->
+
+<section class="examples">
+
+## Examples
+
+<!-- eslint no-undef: "error" -->
+
+```javascript
+var bernoulli = require( '@stdlib/random/array/bernoulli' );
+var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
