For example, to calculate the dot product of every other element in `x` and the first `N` elements of `y` in reverse order, + +```javascript +var Complex64Array = require( '@stdlib/array/complex64' ); + +var x = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] ); +var y = new Complex64Array( [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0 ] ); + +var z = cdotu( 2, x, 2, y, -1 ); +// returns [ -2.0, 14.0 ] +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + + + +```javascript +var Complex64Array = require( '@stdlib/array/complex64' ); + +// Initial arrays... +var x0 = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] ); +var y0 = new Complex64Array( [ 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] ); + +// Create offset views... +var x1 = new Complex64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element +var y1 = new Complex64Array( y0.buffer, y0.BYTES_PER_ELEMENT*2 ); // start at 3rd element + +var z = cdotu( 1, x1, 1, y1, 1 ); +// returns [ -15.0, 80.0 ] +``` + +#### cdotu.ndarray( N, x, strideX, offsetX, y, strideY, offsetY ) + +Calculates the dot product of `x` and `y` using alternative indexing semantics. + +```javascript +var Complex64Array = require( '@stdlib/array/complex64' ); + +var x = new Complex64Array( [ 4.0, 2.0, -3.0, 5.0, -1.0, 7.0 ] ); +var y = new Complex64Array( [ 2.0, 6.0, -1.0, -4.0, 8.0, 9.0 ] ); + +var z = cdotu.ndarray( x.length, x, 1, 0, y, 1, 0 ); +// returns [ -52.0, 82.0 ] +``` + +The function has the following additional parameters: + +- **offsetX**: starting index for `x`. +- **offsetY**: starting index for `y`. + +While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example, to calculate the dot product of every other element in `x` starting from the second element with the last 2 elements in `y` in reverse order + + + +```javascript +var Complex64Array = require( '@stdlib/array/complex64' ); + +var x = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] ); +var y = new Complex64Array( [ 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0 ] ); + +var z = cdotu.ndarray( 2, x, 2, 1, y, -1, y.length-1 ); +// returns [ -40.0, 310.0 ] +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return `0.0 + 0.0i`. +- `cdotu()` corresponds to the [BLAS][blas] level 1 function [`cdotu`][cdotu]. + +
