file not found in current directory
显示 更早的评论
This sounds very similar to other entries in this forum and elsewhere e.g.
But a little different, and those answers don't help me. When I got this message the first time, I realised I had forgotten to copy a file across from a neighbouring folder. (I would hardlink if windows allowed that on network drives, or softlink if matlab could follow windows' softlinks... but I digress.) Even after copying the file, I still get the file not found message. Weirdly, 'edit my_function.m' works!
>> my_function
'my_function' is not found in the current folder or on
the MATLAB path, but exists in:
H:\path\to\nearby_folder
Change the MATLAB current folder or add its folder to the MATLAB
path.
>> exist('my_function')
ans =
0
>> which -all my_function.m
'my_function.m' not found.
>> edit my_function.m
>> ls

What was the current directory when you were doing all of this?
Did you at any time, between these commands, change the current directory from the start to "H:\path\to\nearby_folder", or any other folder or were you in the original folder the whole time?

I ask because I think the post you made has been altered. For example, I doubt that you really have a folder called "H:\path\to\nearby_folder" -- maybe you do have a folder with that exact name, but it seems like a strange folder name to have so that's why I think some things were altered and not a clean unmodified copy and paste from your command window. Again, what is the current folder?

Hello Chris,
By default, MATLAB will cache functions and files for faster finding and executing of them. Generally files newly added to folders will be found properly, but sometimes it needs to be told to rehash before it will detect the new file. That it finds the file with edit and ls likely has more to do with those commands using a different system for finding files than the execution engine.
If rehash doesn't do it for you, try rehash toolboxcache just to be sure. Restarting MATLAB is something of the nuclear option here, but should work in almost all cases.

Thanks for the update. The toolboxcache should only matter if the folder you're changing the files is within the MATLAB installation or local preferences directory. If you are changing files outside of that, and you are seeing rehash by itself failing to affect it reproducibly and consistently, please contact tech support with the reproduction steps.
