undefined function error for builtin toolbox function

2 views (last 30 days)
I've licensed image processing toolbox on Matlab 2021b, and I'm getting the following error (below), with bwareaopen function
Undefined function 'eml_assert_all_constant' for input arguments of type 'double'
Any suggestions on how to resolve this?

Did you install that toolbox when you installed Matlab? If not, run the 2021b installer again and only select the Image Processing Toolbox for installation. It will install just that toolbox into your Matlab install.

If this recurs in the future, you don't need to reinstall. Likely you had a directory on your MATLAB path that contains an implementation used by MATLAB Coder when you try to generate code from the bwareaopen function. If you have the eml subdirectory in toolbox/images/images on your path, remove it from the path.
