+# zdotu
+
+> Calculate the dot product of two double-precision complex floating-point vectors.
+
+
+
+The [dot product][dot-product] (or scalar product) is defined as
+
+
+
+```math
+\mathbf{zx}\cdot\mathbf{zy} = \sum_{i=0}^{N-1} zx_i zy_i = zx_0 zy_0 + zx_1 zy_1 + \ldots + zx_{N-1} zy_{N-1}
+```
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var zdotu = require( '@stdlib/blas/base/zdotu' );
+```
+
+#### zdotu( N, zx, strideX, zy, strideY )
+
+Calculates the dot product of vectors `zx` and `zy`.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var real = require( '@stdlib/complex/float64/real' );
+var imag = require( '@stdlib/complex/float64/imag' );
+
+var zx = new Complex128Array( [ 4.0, 2.0, -3.0, 5.0, -1.0, 7.0 ] );
+var zy = new Complex128Array( [ 2.0, 6.0, -1.0, -4.0, 8.0, 9.0 ] );
+
+var z = zdotu( 3, zx, 1, zy, 1 );
+// returns
+
+var re = real( z );
+// returns -52.0
+
+var im = imag( z );
+// returns 82.0
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **zx**: input [`Complex128Array`][@stdlib/array/complex128].
+- **strideX**: index increment for `zx`.
+- **zy**: input [`Complex128Array`][@stdlib/array/complex128].
+- **strideY**: index increment for `zy`.
+
+The `N` and strides parameters determine which elements in the strided arrays are accessed at runtime. For example, to calculate the dot product of every other value in `zx` and the first `N` elements of `zy` in reverse order,
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var real = require( '@stdlib/complex/float64/real' );
+var imag = require( '@stdlib/complex/float64/imag' );
+
+var zx = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var zy = new Complex128Array( [ 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0 ] );
+
+var z = zdotu( 2, zx, 2, zy, -1 );
+// returns
+
+var re = real( z );
+// returns -2.0
+
+var im = imag( z );
+// returns 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' );
+var real = require( '@stdlib/complex/float64/real' );
+var imag = require( '@stdlib/complex/float64/imag' );
+
+// Initial arrays...
+var zx0 = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var zy0 = new Complex128Array( [ 7.0, 8.0, 9.0, 10.0, 11.0, 12.0 ] );
+
+// Create offset views...
+var zx1 = new Complex128Array( zx0.buffer, zx0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var zy1 = new Complex128Array( zy0.buffer, zy0.BYTES_PER_ELEMENT*2 ); // start at 3th element
+
+var z = zdotu( 1, zx1, 1, zy1, 1 );
+// returns
+
+var re = real( z );
+// returns -15.0
+
+var im = imag( z );
+// returns 80.0
+```
+
+#### zdotu.ndarray( N, zx, strideX, offsetX, zy, strideY, offsetY )
+
+Calculates the dot product of `zx` and `zy` using alternative indexing semantics.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var real = require( '@stdlib/complex/float64/real' );
+var imag = require( '@stdlib/complex/float64/imag' );
+
+var zx = new Complex128Array( [ 4.0, 2.0, -3.0, 5.0, -1.0, 7.0 ] );
+var zy = new Complex128Array( [ 2.0, 6.0, -1.0, -4.0, 8.0, 9.0 ] );
+
+var z = zdotu.ndarray( zx.length, zx, 1, 0, zy, 1, 0 );
+// returns
+
+var re = real( z );
+// returns -52.0
+
+var im = imag( z );
+// returns 82.0
+```
+
+The function has the following additional parameters:
+
+- **offsetX**: starting index for `zx`.
+- **offsetY**: starting index for `zy`.
+
+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 value in `zx` starting from the second value with the last 2 elements in `zy` in reverse order
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var real = require( '@stdlib/complex/float64/real' );
+var imag = require( '@stdlib/complex/float64/imag' );
+
+var zx = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var zy = new Complex128Array( [ 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0 ] ); // eslint-disable-line max-len
+
+var z = zdotu.ndarray( 2, zx, 2, 1, zy, -1, zy.length-1 );
+// returns
+
+var re = real( z );
+// returns -40.0
+
+var im = imag( z );
+// returns 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 zx = filledarrayBy( 10, 'complex128', rand );
+console.log( zx.toString() );
+
+var zy = filledarrayBy( 10, 'complex128', rand );
+console.log( zy.toString() );
+
+var out = zdotu.ndarray( zx.length, zx, 1, 0, zy, -1, zy.length-1 );
+console.log( out.toString() );

+{{alias}}( N, zx, strideX, zy, strideY )
+ Calculate the dot product of two double-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

+
+ If `N <= 0`, the function returns `0 + 0i`.
+
+ Parameters
+ ----------
+ N: integer

+ Second input array.
+
+ strideY: integer
+ Index increment for `zy`.
+
+ Returns
+ -------
+ out: Complex128
+ Scalar constant.
+
+ Examples
+ --------
+ // Standard usage:
