function dcusum( N, sum, x, strideX, offsetX, y, strideY, offsetY ) {
	return dcusumkbn( N, sum, x, strideX, offsetX, y, strideY, offsetY );
}
Computes the cumulative sum of double-precision floating-point strided array elements.

@param {PositiveInteger} N - number of indexed elements
@param {number} sum - initial sum
@param {Float64Array} x - input array
@param {integer} strideX - stride length for `x`
@param {NonNegativeInteger} offsetX - starting index for `x`
@param {Float64Array} y - output array
@param {integer} strideY - stride length for `y`
@param {NonNegativeInteger} offsetY - starting index for `y`
@returns {Float64Array} output array

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

var x = new Float64Array( [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0 ] );
var y = new Float64Array( x.length );

var v = dcusum( 4, 0.0, x, 2, 1, y, 1, 0 );
// returns <Float64Array>[ 1.0, -1.0, 1.0, 5.0, 0.0, 0.0, 0.0, 0.0 ]
