There is no error when I use 2019b. But 2021a generate error message.
What should I do to avoid the error?
Part of my code:
Error message:

Hi Kwanghyun,
I encountered a similar issue when trying to use a saved model in MATLAB R2021a. I tried loading and saving the model again in MATLAB R2021a, and it fixed the error for me.
Please follow the steps given below to address the issue:
  • Load the model using MATLAB‘loadLearnerForCoder’function.
mdl = loadLearnerForCoder('CompactInBedSVM');
  • Save the model using MATLAB ‘saveLearnerForCoder’ function.
saveLearnerForCoder(mdl,'CompactInBedSVMNew');
For detailed information on these functions, please refer to the MATLAB documentation linked below.

Hope this helps
