Approximate translation:
How does the two curves make the border more smooth?

My thought was that to get the smoothness, it would be necessary to adjust the spline end conditions to match between the two curves, something like
temp_x = [x1(3), x1(2), x1(1), x, x1(end-2), x1(end-1), x1(end)];
temp_y = [y1(3), y1(2), y1(1), y, y1(end-2), y1(end-1), y1(end)];
temp_x1 = [x(3), x(2), x(1), x1, x(end-2), x(end-1), x(end)];
temp_y1 = [y(3), y(2), y(1), y1, y(end-2), y(end-1), y(end)];
yi = interp1(temp_x, temp_y, xx, 'spline');
yy = interp1(temp_x1, temp_y1, xy, 'spline');
