What have you tried? I doubt it would be difficult to find the max and min functions.

There are only 2 extreme points. If you want to find local maxima and minima you should try the findpeaks function. Your vector seems a bit too small for local minima and maxima to make sense.

If it is very large,how can I find all min and max.png)

The image you posted doesn't make sense to me. The red markers don't seem to indicate local minima or maxima. So if you're looking to reproduce those red markers I don't know how to help you because your description is insufficient. If you want local minima and maxima, use the findpeaks function.
