Hi, I understand that you want to use the eacfault function to plot equal area critera, but MATLAB does not have this function inbuilt.
You need to either create the function yourself, or you can use any "eacfault.m" open source file.
Here's a link for the open source file: eacfault.m. I've tested this file and it works. Download it and move it to the same path as the file that you're currently working on.
Make sure that the function name in the file and the file name match, otherwise the function won't be recognized.
Hope this helps!
