For my case, it is 'user error'. I do have a dup file name. When I started to remove each file one by one out of my current directory yesterday, I didn't restart Matlab after I removed them so Matlab still thought I had conflicting file in the directory. 'functest.m' was created and ran successfully after I kept only 'funcone.m'.
Given the huge amount of views on this post, it will be really helpful even if Mathwork can do a proper error message with conflicting file names as part of the output. Thank you.
