+# dlasv2
+
+> Compute singular value decomposition of a 2x2 triangular matrix.
+
+
+
+## Usage
+
+```javascript
+var dlasv2 = require( '@stdlib/lapack/base/dlasv2' );
+```
+
+#### dlasv2( F, G, H, out )
+
+Computes singular value decomposition of a 2x2 triangular matrix.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var out = new Float64Array( 6 );
+
+out = dlasv2( 2.0, 3.0, 4.0, out );
+// out => [ 1.5513263285176897, 5.1568776039816795, 0.9664996487646696, 0.25666793515702424, 0.7496781758158659, 0.6618025632357402 ]
+```
+
+The function has the following parameters:
+
+- **F**: the (0,0) element of matrix.
+- **G**: the (0,1) element of matrix.
+- **H**: the (1,1) element of matrix.
+- **out**: [`Float64Array`][mdn-float64array] output array containing `SSMIN`, `SSMAX`, `SNR`, `CSR`, `SNL`, and `CSL` respectively.
+
+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 OUT0 = new Float64Array( [ 0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
+
+// Create offset views...
+var OUT1 = new Float64Array( OUT0.buffer, OUT0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+dlasv2( 2.0, 3.0, 4.0, OUT1 );
+// OUT0 => [ 0.0, 1.5513263285176897, 5.1568776039816795, 0.9664996487646696, 0.25666793515702424, 0.7496781758158659, 0.6618025632357402 ]
+```
+
+#### dlasv2.ndarray( F, G, H, out, strideOut, offsetOut )
+
+Computes singular value decomposition of a 2x2 triangular matrix using alternative indexing semantics.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var out = new Float64Array( 6 );
+
+out = dlasv2.ndarray( 2.0, 3.0, 4.0, out, 1, 0 );
+// out => [ 1.5513263285176897, 5.1568776039816795, 0.9664996487646696, 0.25666793515702424, 0.7496781758158659, 0.6618025632357402 ]
+```
+
+The function has the following additional parameters:
+
+- **strideOut**: stride length for `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,
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var out = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0] );
+
+out = dlasv2.ndarray( 2.0, 3.0, 4.0, out, 1, 1 );
+// out => [ 0.0, 1.5513263285176897, 5.1568776039816795, 0.9664996487646696, 0.25666793515702424, 0.7496781758158659, 0.6618025632357402 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- `dlasv2()` corresponds to the [LAPACK][LAPACK] routine [`dlasv2`][lapack-dlasv2].
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var dlasv2 = require( '@stdlib/lapack/base/dlasv2' );
+
+var out = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+out = dlasv2( 2.0, 3.0, 4.0, out );
+console.log( out );
