+# dlaisnan
+
+> LAPACK auxiliary routine to test input for NaN by comparing two double-precision floating-point arguments for inequality.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var dlaisnan = require( '@stdlib/lapack/base/dlaisnan' );
+```
+
+#### dlaisnan( DIN1, DIN2 )
+
+Tests whether two double-precision floating-point arguments are unequal and thus at least one is NaN.
+
+```javascript
+var bool = dlaisnan( NaN, NaN );
+// returns true
+
+bool = dlaisnan( NaN, 5.0 );
+// returns true
+
+bool = dlaisnan( 5.0, 5.0 );
+// returns false
+```
+
+The function has the following parameters:
+
+-   **DIN1**: first number to compare.
+-   **DIN2**: second number to compare.
+
+</section>
+
+<!-- /.usage -->
+
+<section class="notes">
+
+## Notes
+
+-   `dlaisnan()` corresponds to the [LAPACK][LAPACK] auxiliary routine [`dlaisnan`][lapack-dlaisnan].
+-   This routine is not for general use. It exists solely to avoid over-optimization in `disnan`.
+-   `dlaisnan` checks for NaNs by comparing its two arguments for inequality. `NaN` is the only floating-point value where `NaN != NaN` returns `true`. To check for NaNs, pass the same variable as both arguments (i.e., `dlaisnan( x, x )`).
+-   The function returns `true` whenever the two arguments are unequal, not only when one is NaN. This matches the Fortran reference implementation which simply returns `DIN1.NE.DIN2`.

+# capx
+
+> Add a scalar constant to each element in a single-precision complex floating-point strided array.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var capx = require( '@stdlib/blas/ext/base/capx' );
+```
+
+#### capx( N, alpha, x, strideX )
+
+Adds a scalar constant to each element in a single-precision complex floating-point strided array.
+
+```javascript
+var Complex64Array = require( '@stdlib/array/complex64' );
+var Complex64 = require( '@stdlib/complex/float32/ctor' );
+
+var x = new Complex64Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );
+
+var alpha = new Complex64( 5.0, 0.0 );
+
+capx( x.length, alpha, x, 1 );
+// x => <Complex64Array>[ 3.0, 1.0, 8.0, -5.0, 9.0, 0.0, 4.0, -3.0 ]
+```
+
+The function has the following parameters:
+
+-   **N**: number of indexed elements.
+-   **alpha**: scalar constant.
+-   **x**: input [`Complex64Array`][@stdlib/array/complex64].
+-   **strideX**: stride length.
+
+The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to add a constant to every other element:
+
+```javascript
+var Complex64Array = require( '@stdlib/array/complex64' );
+var Complex64 = require( '@stdlib/complex/float32/ctor' );
+
+var x = new Complex64Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );
+
+var alpha = new Complex64( 5.0, 0.0 );
+
+capx( 3, alpha, x, 2 );
+// x => <Complex64Array>[ 3.0, 1.0, 3.0, -5.0, 9.0, 0.0, -1.0, -3.0 ]
+```
+
+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' );
+var Complex64 = require( '@stdlib/complex/float32/ctor' );
+
+// Initial array:
+var x0 = new Complex64Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] );
+
+// Create an offset view:
+var x1 = new Complex64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Define a scalar constant:
+var alpha = new Complex64( 5.0, 0.0 );
+
+// Add a constant to every other element:
+capx( 2, alpha, x1, 2 );
+// x0 => <Complex64Array>[ 1.0, -2.0, 8.0, -4.0, 5.0, -6.0 ]
+```
+
+#### capx.ndarray( N, alpha, x, strideX, offsetX )
+
+Adds a scalar constant to each element in a single-precision complex floating-point strided array using alternative indexing semantics.
+
+```javascript
+var Complex64Array = require( '@stdlib/array/complex64' );
+var Complex64 = require( '@stdlib/complex/float32/ctor' );
+
+var x = new Complex64Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );
+
+var alpha = new Complex64( 5.0, 0.0 );
+
+capx.ndarray( x.length, alpha, x, 1, 0 );
+// x => <Complex64Array>[ 3.0, 1.0, 8.0, -5.0, 9.0, 0.0, 4.0, -3.0 ]
+```
+
+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 access only the last two elements of the strided array:
+
+```javascript
+var Complex64Array = require( '@stdlib/array/complex64' );
+var Complex64 = require( '@stdlib/complex/float32/ctor' );
+
+var x = new Complex64Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] );
+
+var alpha = new Complex64( 5.0, 0.0 );
+
+capx.ndarray( 3, alpha, x, 2, 1 );
+// x => <Complex64Array>[ 1.0, -2.0, 8.0, -4.0, 5.0, -6.0 ]
+```

+
+{{alias}}( N, alpha, x, strideX )
+    Adds a scalar constant to each element in a single-precision complex
+    floating-point strided array.
+
+    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: Complex64
+        Scalar constant.
+
+    x: Complex64Array
+        Input array.
+
+    strideX: integer
+        Stride length.
+
+    Returns
+    -------
+    x: Complex64Array
+        Input array.
+
+    Examples
+    --------
+    // Standard Usage:
+    > var buf = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];
+    > var x = new {{alias:@stdlib/array/complex64}}( buf );
+    > var alpha = new {{alias:@stdlib/complex/float32/ctor}}( 5.0, 0.0 );
+    > {{alias}}( x.length, alpha, x, 1 );
+    > x
+    <Complex64Array>[ 3.0, 1.0, 8.0, -5.0, 9.0, 0.0, 4.0, -3.0 ]
+
+    // Using `N` and stride parameters:
+    > x = new {{alias:@stdlib/array/complex64}}( buf );
+    > alpha = new {{alias:@stdlib/complex/float32/ctor}}( 5.0, 0.0 );
+    > {{alias}}( 3, alpha, x, 2 );
+    > x
+    <Complex64Array>[ 3.0, 1.0, 3.0, -5.0, 9.0, 0.0, -1.0, -3.0 ]
+
+    // Using view offsets:
+    > var buf0 = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ];
+    > var x0 = new {{alias:@stdlib/array/complex64}}( buf0 );
+    > var offset = x0.BYTES_PER_ELEMENT * 1;
+    > var x1 = new {{alias:@stdlib/array/complex64}}( x0.buffer, offset );
+    > alpha = new {{alias:@stdlib/complex/float32/ctor}}( 5.0, 0.0 );

+
+
+{{alias}}.ndarray( N, alpha, x, strideX, offsetX )
+    Adds a scalar constant to each element in a single-precision complex
+    floating-point strided array 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: Complex64
+        Scalar constant.
+
+    x: Complex64Array
+        Input array.
+
+    strideX: integer
+        Stride length.
+
+    offsetX: integer
+        Starting index.
+
+    Returns
+    -------
+    x: Complex64Array
+        Input array.

-# dlaisnan
-
-> LAPACK auxiliary routine to test input for NaN by comparing two double-precision floating-point arguments for inequality.
-
-<section class="usage">
-
-## Usage
-
-```javascript
-var dlaisnan = require( '@stdlib/lapack/base/dlaisnan' );
-```
-
-#### dlaisnan( DIN1, DIN2 )
-
-Tests input for NaN by comparing two double-precision floating-point arguments for inequality.
-
-```javascript
-var bool = dlaisnan( NaN, NaN );
-// returns true
-
-bool = dlaisnan( NaN, 5.0 );
-// returns true
-
-bool = dlaisnan( 5.0, 5.0 );
-// returns false
-```
-
-The function has the following parameters:
-
--   **DIN1**: first input number.
--   **DIN2**: second input number.

-## Notes
-
--   `dlaisnan()` corresponds to the [LAPACK][lapack] auxiliary routine [`dlaisnan`][lapack-dlaisnan].
--   This routine is not for general use. It exists solely to avoid over-optimization in [`disnan`][lapack-disnan].
--   `dlaisnan` checks for NaNs by comparing its two arguments for inequality. `NaN` is the only floating-point value where `NaN !== NaN` returns `true`. To check for NaNs, pass the same variable as both arguments (i.e., `dlaisnan( x, x )`).
--   The function returns `true` whenever the two arguments are unequal, not only when one is `NaN`. This matches the Fortran reference implementation which simply returns `DIN1.NE.DIN2`.
