An UndefinedFunction error was thrown on the workers for 'wdenoise'

Hi,

Thank you so much for sharing this code! I am trying to run the min1pipe.m using the demo_data.tif and reach this error near the end. Any ideas for how to fix this? Thank you!

An UndefinedFunction error was thrown on the workers for 'wdenoise'. This might be because
the file containing 'wdenoise' is not accessible on the workers. Use addAttachedFiles(pool,
files) to specify the required files to be attached. See the documentation for
'parallel.Pool/addAttachedFiles' for more details.

Thanks for the question. Please check if you installed wavelet toolbox. Please also check the other dependent toolboxes here.

[aozgur360]

Thank you, I have all of the toolboxes installed that were mentioned, including wavelet toolbox. Not sure why I am getting this error

[JinghaoLu]

Well you can try typing "edit wdenoise" in the matlab command line and see if you can call that function without problem.

I also have the same problem (UndefinedFunction error about wdenoise).
I typed "edit wdenoise" and it said there is no wdenoise.m file. But I'm very sure I have the wavelet toolbox and I can found it in the toolbox folder. May be my Matlab can not found the wdenoise in wavelet toolbox, but why?

[JinghaoLu]

@vetLiaing Did you verify that the toolbox is in matlab path?

[vetLiaing]

All my toolboxs are in the root folder of matlab. I installed them at the same time I install matlab.
I tried add the wavelet toolbox in to the path, but the problem is still happened.

@vetLiaing I found this: https://www.mathworks.com/matlabcentral/answers/5200-undefined-function-or-method-for-input-arguments-of-type-double

[vetLiaing]

I tried the earlier version of Min1pipe and it's no problem to run it. The new version might not be run well on old Matlab? (I'm using 2016b). but anyway I can process my video with Min1pipe. Thank you very much.

[JinghaoLu]

@vetLiaing please try not to use the previous version. And from the readme page of the MIN1PIPE repo you can see that the software recommendation is matlab 2017 and later, so combining the link I shared with you, you might have license issue on a older matlab.
