+# dcartesianPower
+
+> Compute the Cartesian power for a double-precision floating-point strided array.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var dcartesianPower = require( '@stdlib/blas/ext/base/dcartesian-power' );
+```
+
+#### dcartesianPower( N, k, x, strideX, out, LDO )
+
+Computes the Cartesian power for a double-precision floating-point strided array.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 2.0 ] );
+var out = new Float64Array( 8 );
+
+dcartesianPower( x.length, 2, x, 1, out, 2 );
+// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ]
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **k**: power.
+- **x**: input [`Float64Array`][@stdlib/array/float64].
+- **strideX**: stride length for `x`.
+- **out**: output [`Float64Array`][@stdlib/array/float64].
+- **LDO**: stride length for the leading dimension of `out`.
+
+The `N`, `k`, and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to compute the Cartesian power of every other element:
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 0.0, 2.0, 0.0 ] );
+var out = new Float64Array( 8 );
+
+dcartesianPower( 2, 2, x, 2, out, 2 );
+// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ]
+```
+
+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' );
+
+// Initial arrays...
+var x0 = new Float64Array( [ 0.0, 1.0, 2.0 ] );
+var out0 = new Float64Array( 8 );
+
+// Create offset views...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+dcartesianPower( 2, 2, x1, 1, out0, 2 );
+// out0 => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ]
+```
+
+
+
+#### dcartesianPower.ndarray( N, k, x, strideX, offsetX, out, strideOut1, strideOut2, offsetOut )
+
+
+
+Computes the Cartesian power for a double-precision floating-point strided array using alternative indexing semantics.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 2.0 ] );
+var out = new Float64Array( 8 );
+
+dcartesianPower.ndarray( x.length, 2, x, 1, 0, out, 2, 1, 0 );
+// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ]
+```
+
+The function has the following additional parameters:
+
+- **offsetX**: starting index for `x`.
+- **strideOut1**: stride length for the first dimension of `out`.
+- **strideOut2**: stride length for the second dimension of `out`.
+- **offsetOut**: starting index for `out`.
+
+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 compute the Cartesian power of every other value in the strided input array starting from the second value:
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 0.0, 1.0, 2.0 ] );
+var out = new Float64Array( 8 );
+
+dcartesianPower.ndarray( 2, 2, x, 1, 1, out, 2, 1, 0 );
+// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- If `N <= 0` or `k <= 0`, both functions return `out` unchanged.
+- The output array must contain at least `N^k * k` elements.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var dcartesianPower = require( '@stdlib/blas/ext/base/dcartesian-power' );
+
+var x = new Float64Array( [ 1.0, 2.0 ] );
+console.log( x );
+
+var out = new Float64Array( 24 );
+
+dcartesianPower( x.length, 3, x, 1, out, 3 );
+console.log( out );
+```

+{{alias}}( N, k, x, strideX, out, LDO )
+ Computes the Cartesian power for a double-precision floating-point strided
+ array.
+
+ The `N`, `k`, and stride parameters determine which elements in the strided
+ arrays are accessed at runtime.
+
+ If `N <= 0` or `k <= 0`, the function returns `out` unchanged.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ k: integer
+ Power.
+
+ x: Float64Array
+ Input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ out: Float64Array
+ Output array.
+
+ LDO: integer
+ Stride length for the leading dimension of `out`.
+
+ Returns
+ -------
+ out: Float64Array
+ Output array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0 ] );
+ > var out = new {{alias:@stdlib/array/float64}}( 8 );
+ > {{alias}}( x.length, 2, x, 1, out, 2 )
+ [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ]

+ > out = new {{alias:@stdlib/array/float64}}( 8 );
+ > {{alias}}( 2, 2, x, 2, out, 2 )

+
+
+{{alias}}.ndarray( N, k, x, strideX, offsetX, out, so1, so2, oo )
+ Computes the Cartesian power for a double-precision floating-point strided
+ array using alternative indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, the offset parameters support indexing semantics based on starting
+ indices.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ k: integer
+ Power.
+
+ x: Float64Array
+ Input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ offsetX: integer
+ Starting index for `x`.
+
+ out: Float64Array
+ Output array.
+
+ so1: integer
+ Stride length for the first dimension of `out`.
+
+ so2: integer
+ Stride length for the second dimension of `out`.
+
+ oo: integer
+ Starting index for `out`.
+
+ Returns
+ -------
+ out: Float64Array
+ Output array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0 ] );
+ > var out = new {{alias:@stdlib/array/float64}}( 8 );
+ > {{alias}}.ndarray( x.length, 2, x, 1, 0, out, 2, 1, 0 )
