matlab - 如何在matlab中用最后两点的斜率扩展绘图？

Question

如图，如何使曲线1以最后两点的斜率与X轴相接触？

生成上图的代码

X1 = linspace(2,3,20);
Y1 = linspace(1/1000, 1,20);
Y1Dash = flip(Y1);
X2 = linspace(14,15,30);
Y2 = linspace(1/10000, 1,30);
Y2Dash = flip(Y2);
figure;semilogy(X1, Y1Dash, "-r*");hold on;grid on;
semilogy(X2, Y2Dash, "-r*");hold off;
legend("curve1", "Curve2");
