+## Usage
+
+```javascript
+var srev = require( '@stdlib/blas/ext/base/ndarray/srev' );
+```
+
+#### srev( arrays )
+
+Reverses the elements of a one-dimensional single-precision floating-point ndarray.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = new Float32Array( [ 1.0, 2.0, 3.0 ] );
+var x = new ndarray( 'float32', xbuf, [ 3 ], [ 1 ], 0, 'row-major' );
+
+srev( [ x ] );
+// xbuf => <Float32Array>[ 3.0, 2.0, 1.0 ]
+```
+
+The function accepts the following arguments:
+
+-   **arrays**: array-like object containing one one-dimensional `Float32` ndarray.
