function dmediansorted( N, x, strideX ) {
	return ndarray( N, x, strideX, stride2offset( N, strideX ) );
}
Computes the median value of a sorted double-precision floating-point strided array.

@param {PositiveInteger} N - number of indexed elements
@param {Float64Array} x - sorted input array
@param {integer} strideX - stride length
@returns {number} median value

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

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

var v = dmediansorted( x.length, x, 1 );
// returns 2.0
