+# zdotu
+
+> Calculate the dot product of two single-precision complex floating-point vectors.
+
+
+
+The [dot product][dot-product] (or scalar product) is defined as
+
+
+
+```math
+\mathbf{x}\cdot\mathbf{y} = \sum_{i=0}^{N-1} x_i y_i = x_0 y_0 + x_1 y_1 + \ldots + x_{N-1} y_{N-1}
+```
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var zdotu = require( '@stdlib/blas/base/zdotu' );
+```
+
+#### zdotu( N, x, strideX, y, strideY )
+
+Calculates the dot product of vectors `x` and `y`.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+
+var x = new Complex128Array( [ 4.0, 2.0, -3.0, 5.0, -1.0, 7.0 ] );
+var y = new Complex128Array( [ 2.0, 6.0, -1.0, -4.0, 8.0, 9.0 ] );
+
+var z = zdotu( 3, x, 1, y, 1 );
+// returns [ -52.0, 82.0 ]
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **x**: input [`Complex128Array`][@stdlib/array/complex128].
+- **strideX**: stride length for `x`.
+- **y**: input [`Complex128Array`][@stdlib/array/complex128].
+- **strideY**: stride length for `y`.
+
+The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. 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 Complex128Array = require( '@stdlib/array/complex128' );
+
+var x = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var y = new Complex128Array( [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0 ] );
+
+var z = zdotu( 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 Complex128Array = require( '@stdlib/array/complex128' );
+
+// Initial arrays...
+var x0 = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var y0 = new Complex128Array( [ 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] );
+
+// Create offset views...
+var x1 = new Complex128Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var y1 = new Complex128Array( y0.buffer, y0.BYTES_PER_ELEMENT*2 ); // start at 3rd element
+
+var z = zdotu( 1, x1, 1, y1, 1 );
+// returns [ -15.0, 80.0 ]
+```
+
+#### zdotu.ndarray( N, x, strideX, offsetX, y, strideY, offsetY )
+
+Calculates the dot product of `x` and `y` using alternative indexing semantics.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+
+var x = new Complex128Array( [ 4.0, 2.0, -3.0, 5.0, -1.0, 7.0 ] );
+var y = new Complex128Array( [ 2.0, 6.0, -1.0, -4.0, 8.0, 9.0 ] );
+
+var z = zdotu.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 Complex128Array = require( '@stdlib/array/complex128' );
+
+var x = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var y = new Complex128Array( [ 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0 ] );
+
+var z = zdotu.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`.
+- `zdotu()` corresponds to the [BLAS][blas] level 1 function [`zdotu`][zdotu].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/base/discrete-uniform' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var filledarrayBy = require( '@stdlib/array/filled-by' );
+var zdotu = require( '@stdlib/blas/base/zdotu' );
+
+function rand() {
+ return new Complex128( discreteUniform( 0, 10 ), discreteUniform( -5, 5 ) );
+}
+
+var x = filledarrayBy( 10, 'complex128', rand );
+console.log( x.toString() );
+
+var y = filledarrayBy( 10, 'complex128', rand );
+console.log( y.toString() );
+
+// Compute the dot product:
+var out = zdotu( x.length, x, 1, y, -1 );
+console.log( out.toString() );
+
+// Compute the dot product using alternative indexing semantics:
+out = zdotu.ndarray( x.length, x, 1, 0, y, -1, y.length-1 );
+console.log( out.toString() );
+```

+{{alias}}( N, x, strideX, y, strideY )
+ Computes the dot product of two single-precision complex floating-point
+ vectors.
+
+ The `N` and stride parameters determine which elements in the strided
+ arrays are accessed at runtime.
+
+ Indexing is relative to the first index. To introduce an offset, use a
+ typed array view.
+
+ If `N <= 0`, the function returns `0`.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ x: Complex128Array
+ First input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ y: Complex128Array
+ Second input array.
+
+ strideY: integer
+ Stride length for `y`.
+
+ Returns
+ -------
+ out: Complex128
+ Dot product.
+
+ Examples
+ --------
+ // Standard usage:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0 ] );
+ > var y = new {{alias:@stdlib/array/complex128}}( [ 6.0, 7.0, 8.0, 9.0 ] );
+ > var z = {{alias}}( x.length, x, 1, y, 1 )
+ [ -20.0, 78.0 ]
+
+ // Advanced indexing:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+ > var y = new {{alias:@stdlib/array/complex128}}( [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0 ] );
+ > var z = {{alias}}( 2, x, 2, y, -1 )
+ [ -2.0, 14.0 ]
+
+ // Using typed array views:
+ > var x0 = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+ > var y0 = new {{alias:@stdlib/array/complex128}}( [ 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] );
+ > var x1 = new {{alias:@stdlib/array/complex128}}( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
+ > var y1 = new {{alias:@stdlib/array/complex128}}( y0.buffer, y0.BYTES_PER_ELEMENT*2 );
+ > var z = {{alias}}( 1, x1, 1, y1, 1 )
+ [ -15.0, 80.0 ]
+
+
+{{alias}}.ndarray( N, x, strideX, offsetX, y, strideY, offsetY )
+ Computes the dot product of two single-precision complex floating-point
+ vectors using alternative indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, offset parameters support indexing based on starting indices.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ x: Complex128Array
+ First input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ offsetX: integer
+ Starting index for `x`.
+
+ y: Complex128Array
+ Second input array.
+
+ strideY: integer
+ Stride length for `y`.
+
+ offsetY: integer
+ Starting index for `y`.
+
+ Returns
+ -------
+ out: Complex128
+ Dot product.
+
+ Examples
+ --------
+ // Standard usage:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0 ] );
+ > var y = new {{alias:@stdlib/array/complex128}}( [ 6.0, 7.0, 8.0, 9.0 ] );
+ > var z = {{alias}}.ndarray( x.length, x, 1, 0, y, 1, 0 )
+ [ -20.0, 78.0 ]
+
+ // Advanced indexing:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+ > var y = new {{alias:@stdlib/array/complex128}}( [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0 ] );
+ > var z = {{alias}}.ndarray( 1, x, 2, 1, y, -1, y.length-1 )
+ [ -1.0, 7.0 ]
