git运行shell文件时出错，如何解决？

Question

使用git运行dineof.sh的shell文件进行dineof处理时，出现错误Error with _saupd, info=-3，Check documentation in _saupd，可以输出最后的nc文件结果，但是在matlab中无法使用，请问有没有什么解决方法。

Answer 1

docs/troubleshooting.md里提到这个问题，并给出了解决方案，你可以看看。

Another common problem is when you start to see this message appear in the screen when you run DINEOF:
Error with _saupd, info = -3
Check documentation in _saupd
This one is also simple to solve: you need to specify in dineof.init the number of modes to be calculated (nev), and the Kryvlov space (ncv), which need to be smaller than the temporal size of your data, AND, ncv > nev+5. If one or both of these conditions is not met, the above message will appear.
