在 MATLAB Online 中打开

The function you want is in the File Exchange: normalise2dpts(pts) (link). You can download it through the linked page.

Also, MATLAB is case sensitive, so you will have to call it as:

[p2,t2] = normalise2dpts(p2);

Are you running it from the folder you downloaded it to? Did you add that folder to the path?

You have to download it and copy it to your MATLAB user path. In Windows, this is: ‘C:\Users\-UserName-\Documents\MATLAB\’. Then you should be able to use it.
