+# csumkbn
+
+> Compute the sum of all elements in a one-dimensional single-precision complex floating-point ndarray using an improved Kahan–Babuška algorithm.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var csumkbn = require( '@stdlib/blas/ext/base/ndarray/csumkbn' );
+```
+
+#### csumkbn( arrays )
+
+Computes the sum of all elements in a one-dimensional single-precision complex floating-point ndarray using an improved Kahan–Babuška algorithm.
+
+```javascript
+var Complex64Array = require( '@stdlib/array/complex64' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = new Complex64Array( [ 1.0, -2.0, 2.0, 3.0 ] );
+var x = new ndarray( 'complex64', xbuf, [ 2 ], [ 1 ], 0, 'row-major' );
+
+var v = csumkbn( [ x ] );
+// returns [ 3.0, 1.0 ]
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing a one-dimensional input ndarray.
+
+
+
+
+
+
+
+## Notes
+
+- If provided an empty one-dimensional ndarray, the function returns `0.0 + 0.0i`.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var Complex64Array = require( '@stdlib/array/complex64' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var csumkbn = require( '@stdlib/blas/ext/base/ndarray/csumkbn' );
+
+var xbuf = discreteUniform( 10, -50, 50, {
+ 'dtype': 'float32'
+});
+xbuf = new Complex64Array( xbuf );
+
+var x = new ndarray( 'complex64', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
+console.log( ndarray2array( x ) );
+
+var v = csumkbn( [ x ] );
+console.log( v );
+```
