}
Returns an updated sum of squares represented in scaled form.

@param {NonNegativeInteger} N - number of indexed elements
@param {Float64Array} X - input array
@param {integer} strideX - stride length for `X`
@param {number} scale - scaling factor
@param {number} sumsq - basic sum of squares from which output is factored out
@returns {Float64Array} output array

@example
var Float64Array = require( '@stdlib/array/float64' );

var X = new Float64Array( [ 1.0, 2.0, 3.0, 4.0 ] );

var out = dlassq( 4, X, 1, 1.0, 0.0 );
// returns <Float64Array>[ 1.0, 30.0 ]
