当我尝试绘制类似z =（x，y）的3D函数时，Matlab崩溃（关闭），只要该函数涉及以下条件一起：
例如，以下代码无效：
[x,y] = meshgrid(0.01:.01:0.99);
z=x*y^2;
surf(z)
如果我使用mesh而不是surf，也会发生同样的情况。通常，您会发现有关表示法的错误。
这似乎是Matlab的一个错误。自动崩溃报告包含以下内容：

A technical support engineer might contact you with further information.
Thank you for your help.
在本论坛的建议中，我提交了一份服务请求。显然，我通过使用正确的点符号解决了我的问题。然而，无论任何错误的符号，Matlab都不应该崩溃。我会在收到更多信息并删除或回答此问题后更新此帖子。
