/**
* Computes the integral of a double-precision floating-point strided array using the trapezoidal rule and alternative indexing semantics.
*
* ## Notes
*
* - The function computes an approximation of the integral using the trapezoidal rule whose accuracy depends on the sample point spacing and the smoothness of the underlying function.
*
* @param {NonNegativeInteger} N - number of indexed elements
* @param {Float64Array} x - first input array
* @param {integer} strideX - stride length for `x`
* @param {NonNegativeInteger} offsetX - starting index for `x`
* @param {Float64Array} y - second input array
* @param {integer} strideY - stride length for `y`
* @param {NonNegativeInteger} offsetY - starting index for `y`
* @returns {number} integral approximation
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var x = new Float64Array( [ 0.0, 1.0, 2.0, 3.0 ] );
* var y = new Float64Array( [ 0.0, 1.0, 4.0, 9.0 ] );
*
* var out = dtrapezoid( x.length, x, 1, 0, y, 1, 0 );
* // returns 9.5
