Question

我用matlab画了一副三维图，怎么通过输入x，y坐标获取z的值，然后输出存到制定文件，谢谢！

当然，利用data cursor可以显示图像的三维坐标，但我需要的是输入任意（x，y），输出对应的（x，y，z），求大神帮助，谢谢！

具体程序语言和图像如下：
x=[2.026558299 5.039425858 10.09499876 15.225128542 20.22006344 25.32354843 30.4286424];
y=[5 10 15 20 25 30 35 40 45 50 55 60 65 70];
z=[2.025943292 5.037926606 10.08389257 15.19318378 20.18776627 25.28111031 30.37787512;
