For example, to traverse every other value, + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] ); + +var out = dzasum( 2, x, 2 ); +// returns 7.0 +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +// Initial array: +var x0 = new Complex128Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] ); + +// Create an offset view: +var x1 = new Complex128Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element + +// Compute the sum of absolute values: +var out = dzasum( 2, x1, 1 ); +// returns 18.0 +``` + +#### dzasum.ndarray( N, x, strideX, offset ) + +Computes the sum of the absolute values of the real and imaginary components of a double-precision complex floating-point vector using alternative indexing semantics. + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ 0.3, 0.1, 0.5, 0.0, 0.0, 0.5, 0.0, 0.2 ] ); + +var out = dzasum.ndarray( 4, x, 1, 0 ); +// returns ~1.6 +``` + +The function has the following additional parameters: + +- **offsetX**: starting index. + +While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameter supports indexing semantics based on a starting index. For example, to start from the second index, + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] ); + +var out = dzasum.ndarray( 2, x, 1, 1 ); +// returns 18.0 +``` + +
