+# zfill
+
+> Fill a double-precision complex floating-point strided array with a specified scalar constant.
+
+
+
+## Usage
+
+```javascript
+var zfill = require( '@stdlib/blas/ext/base/zfill' );
+```
+
+#### zfill( N, alpha, x, stride )
+
+Fills a double-precision complex floating-point strided array `x` with a specified scalar constant `alpha`.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var realf = require( '@stdlib/complex/float64/real' );
+var imagf = require( '@stdlib/complex/float64/imag' );
+
+var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var x = new Complex128Array( arr );
+
+var alpha = new Complex128( 10.0, 10.0 );
+
+zfill( x.length, alpha, x, 1 );
+
+var y = x.get( 0 );
+// returns
+
+var re = realf( y );
+// returns 10.0
+
+var im = imagf( y );
+// returns 10.0
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **alpha**: scalar constant.
+- **x**: input [`Complex128Array`][@stdlib/array/complex128].
+- **stride**: index increment.
+
+The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to fill every other element
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var realf = require( '@stdlib/complex/float64/real' );
+var imagf = require( '@stdlib/complex/float64/imag' );
+
+var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var x = new Complex128Array( arr );
+
+var alpha = new Complex128( 10.0, 10.0 );
+
+zfill( 2, alpha, x, 2 );
+
+var y = x.get( 0 );
+// returns
+
+var re = realf( y );
+// returns 10.0
+
+var im = imagf( y );
+// returns 10.0
+
+y = x.get( 1 );
+// returns
+
+re = realf( y );
+// returns 3.0
+
+im = imagf( y );
+// returns 4.0
+```
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var realf = require( '@stdlib/complex/float64/real' );
+var imagf = require( '@stdlib/complex/float64/imag' );
+
+// Create the underlying floating-point array
+var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+
+// Initial array:
+var x0 = new Complex128Array( arr );
+
+// Create an offset view:
+var x1 = new Complex128Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Define a scalar constant:
+var alpha = new Complex128( 10.0, 10.0 );
+
+// Fill every other element:
+zfill( 2, alpha, x1, 2 );
+
+var y = x0.get( 0 );
+// returns
+
+var re = realf( y );
+// returns 1.0
+
+var im = imagf( y );
+// returns 2.0
+
+y = x0.get( 1 );
+// returns
+
+re = realf( y );
+// returns 10.0
+
+im = imagf( y );
+// returns 10.0
+```
+
+#### zfill.ndarray( N, alpha, x, stride, offset )
+
+Fills a double-precision complex floating-point strided array `x` with a specified scalar constant `alpha` using alternative indexing semantics.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var realf = require( '@stdlib/complex/float64/real' );
+var imagf = require( '@stdlib/complex/float64/imag' );
+
+var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
+var x = new Complex128Array( arr );
+
+var alpha = new Complex128( 10.0, 10.0 );
+
+zfill.ndarray( x.length, alpha, x, 1, 0 );
+
+var y = x.get( 0 );
+// returns
+
+var re = realf( y );
+// returns 10.0
+
+var im = imagf( y );
+// returns 10.0
+```
+
+The function has the following additional parameters:
+
+- **offset**: 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 access only the last two elements of the strided array
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var realf = require( '@stdlib/complex/float64/real' );
+var imagf = require( '@stdlib/complex/float64/imag' );
+
+var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x = new Complex128Array( arr );
+
+var alpha = new Complex128( 10.0, 10.0 );
+
+zfill.ndarray( 2, alpha, x, 1, x.length-2 );
+
+var y = x.get( 0 );
+// returns
+
+var re = realf( y );
+// returns 1.0
+
+var im = imagf( y );
+// returns 2.0
+
+y = x.get( 1 );
+// returns
+
+re = realf( y );
+// returns 10.0
+
+im = imagf( y );
+// returns 10.0
+
+y = x.get( 2 );
+// returns
+
+re = realf( y );
+// returns 10.0
+
+im = imagf( y );
+// returns 10.0
+```
+
+
+
+
+
+
+
+## Notes
+
+- If `N <= 0`, both functions return the strided array unchanged.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/base/discrete-uniform' );
+var filledarrayBy = require( '@stdlib/array/filled-by' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var zfill = require( '@stdlib/blas/ext/base/zfill' );
+
+function rand() {
+ return new Complex128( discreteUniform( 0, 10 ), discreteUniform( -5, 5 ) );
+}
+
+var x = filledarrayBy( 10, 'complex128', rand );
+var alpha = new Complex128( 10.0, 10.0 );
+
+zfill( x.length, alpha, x, 1 );
+console.log( x.get( 0 ).toString() );
+```

+{{alias}}( N, alpha, x, stride )
+ Fills a double-precision complex floating-point strided array with a
+ specified scalar constant.
+
+ The `N` and stride parameters determine which elements in the strided array
+ are accessed at runtime.
+
+ Indexing is relative to the first index. To introduce an offset, use typed
+ array views.
+
+ If `N <= 0`, the function returns `x` unchanged.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ alpha: Complex128
+ Constant.
+
+ x: Complex128Array
+ Input array.
+
+ stride: integer
+ Index increment.
+
+ Returns
+ -------
+ x: Complex128Array
+ Input array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0 ] );
+ > var alpha = new {{alias:@stdlib/complex/float64/ctor}}( 5.0, -5.0 );
+ > {{alias}}( x.length, alpha, x, 1 );
+ > var z = x.get( 0 );
+ > var re = {{alias:@stdlib/complex/float64/real}}( z )
+ 5.0
+ > var im = {{alias:@stdlib/complex/float64/imag}}( z )
+ -5.0
+
+ // Using `N` and stride parameters:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+ > var alpha = new {{alias:@stdlib/complex/float64/ctor}}( 5.0, -5.0 );
+ > {{alias}}( 2, alpha, x, 2 );
+ > var z = x.get( 0 );
+ > var re = {{alias:@stdlib/complex/float64/real}}( z )
+ 5.0
+ > var im = {{alias:@stdlib/complex/float64/imag}}( z )
+ -5.0
+ > z = x.get( 1 );

+ > var x1 = new {{alias:@stdlib/array/complex128}}( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
+ > var alpha = new {{alias:@stdlib/complex/float64/ctor}}( 5.0, -5.0 );

+
+
+{{alias}}.ndarray( N, alpha, x, stride, offset )
+ Fills a double-precision complex floating-point strided array with a
+ specified scalar constant using alternative indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, the offset parameter supports indexing semantics based on a starting
+ index.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ alpha: Complex128
+ Constant.
+
+ x: Complex128Array
+ Input array.
+
+ stride: integer
+ Index increment.
+
+ offset: integer
+ Starting index.
+
+ Returns
+ -------
+ x: Complex128Array
+ Input array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 1.0, 2.0, 3.0, 4.0 ] );
+ > var alpha = new {{alias:@stdlib/complex/float64/ctor}}( 2.0, 2.0 );

+ > var z = x.get( 0 );
+ > var re = {{alias:@stdlib/complex/float64/real}}( z )
