+# dlartv
+
+> Apply a vector of real plane rotations to elements of real vectors `X` and `Y`.
+
+
+
+## Usage
+
+```javascript
+var dlartv = require( '@stdlib/lapack/base/dlartv' );
+```
+
+#### dlartv( N, X, strideX, Y, strideY, C, S, strideCS )
+
+Applies a vector of real plane rotations to elements of real vectors `X` and `Y`.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var X = new Float64Array( [ 1.0, 1.0 ] );
+var Y = new Float64Array( [ 1.0, 1.0 ] );
+var C = new Float64Array( [ 1.0, 1.0 ] );
+var S = new Float64Array( [ 0.0, 0.0 ] );
+
+dlartv( 2, X, 1, Y, 1, C, S, 1 );
+// X => [ 1.0, 1.0 ]
+// Y => [ 1.0, 1.0 ]
+```
+
+The function has the following parameters:
+
+- **N**: number of plane rotations to apply.
+- **X**: first input [`Float64Array`][mdn-float64array].
+- **strideX**: `X` stride length.
+- **Y**: second input [`Float64Array`][mdn-float64array].
+- **strideY**: `Y` stride length.
+- **C**: input [`Float64Array`][mdn-float64array] containing the cosine values of the plane rotations.
+- **S**: input [`Float64Array`][mdn-float64array] containing the sine values of the plane rotations.
+- **strideCS**: `CS` stride length.
+
+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, 1.0 ] );
+var Y0 = new Float64Array( [ 0.0, 1.0, 1.0 ] );
+var C0 = new Float64Array( [ 0.0, 1.0, 1.0 ] );
+var S0 = new Float64Array( [ 0.0, 0.0, 0.0 ] );
+
+// Create offset views...
+var X1 = new Float64Array( X0.buffer, X0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var Y1 = new Float64Array( Y0.buffer, Y0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var C1 = new Float64Array( C0.buffer, C0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var S1 = new Float64Array( S0.buffer, S0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+dlartv( 2, X1, 1, Y1, 1, C1, S1, 1 );
+// X0 => [ 0.0, 1.0, 1.0 ]
+// Y0 => [ 0.0, 1.0, 1.0 ]
+```
+
+#### dlartv.ndarray( N, X, sx, ox, Y, sy, oy, C, sc, oc, S, ss, os )
+
+Applies a vector of real plane rotations to elements of real vectors `X` and `Y` using alternative semantic indexing.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var X = new Float64Array( [ 1.0, 1.0 ] );
+var Y = new Float64Array( [ 1.0, 1.0 ] );
+var C = new Float64Array( [ 1.0, 1.0 ] );
+var S = new Float64Array( [ 0.0, 0.0 ] );
+
+dlartv.ndarray( 2, X, 1, 0, Y, 1, 0, C, 1, 0, S, 1, 0 );
+// X => [ 1.0, 1.0 ]
+// Y => [ 1.0, 1.0 ]
+```
+
+The function has the following parameters:
+
+- **N**: number of plane rotations to apply.
+- **X**: first input [`Float64Array`][mdn-float64array].
+- **sx**: `X` stride length.
+- **ox**: starting index for `X`.
+- **Y**: second input [`Float64Array`][mdn-float64array].
+- **sy**: `Y` stride length.
+- **oy**: starting index for `Y`.
+- **C**: input [`Float64Array`][mdn-float64array] containing the cosine values of the plane rotations.
+- **sc**: `C` stride length.
+- **oc**: starting index for `C`.
+- **S**: input [`Float64Array`][mdn-float64array] containing the sine values of the plane rotations.
+- **ss**: `S` stride length.
+- **os**: starting index for `S`.
+
+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,
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var X = new Float64Array( [ 1.0, 1.0 ] );
+var Y = new Float64Array( [ 1.0, 1.0 ] );
+var C = new Float64Array( [ 1.0, 1.0 ] );
+var S = new Float64Array( [ 0.5, 0.4 ] );
+
+dlartv.ndarray( 2, X, -1, 1, Y, 1, 0, C, 1, 0, S, 1, 0 );
+// X => [ 1.4, 1.5 ]
+// Y => [ 0.5, 0.6 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- `dlartv()` corresponds to the [LAPACK][lapack] routine [`dlartv`][lapack-dlartv].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var dlartv = require( '@stdlib/lapack/base/dlartv' );
+
+var X = new Float64Array( [ 1.0, 1.0 ] );
+var Y = new Float64Array( [ 1.0, 1.0 ] );
+var C = new Float64Array( [ 1.0, 1.0 ] );
+var S = new Float64Array( [ 0.5, 0.5 ] );
+
+X = dlartv( 2, X, 1, Y, 1, C, S, 1 );
+console.log( X );
+console.log( Y );
