/**
* Computes singular value decomposition of a 2x2 upper triangular matrix.
*
* ## Notes
*
* - `abs(SSMAX)` is the larger singular value.
* - `abs(SSMIN)` is the smaller singular value.
* - (`CSL`,`SNL`) and (`CSR`,`SNR`) are the left and right singular vectors for `abs(SSMAX)`.
*
* @param {number} F - the (0,0) element of matrix
* @param {number} G - the (0,1) element of matrix
* @param {number} H - the (1,1) element of matrix
* @param {Float64Array} out - output array containing `SSMIN`, `SSMAX`, `SNR`, `CSR`, `SNL`, and `CSL` respectively
* @returns {Float64Array} output array
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var out = new Float64Array( 6 );
*
* dlasv2( 2.0, 3.0, 4.0, out );
* // out => <Float64Array>[ ~1.5513, ~5.1569, ~0.9665, ~0.2567, ~0.7497, ~0.6618 ]
