The shapley command (https://www.mathworks.com/help/stats/shapley.html) was released in R2021a. The sidebar indicates you were using R2020a. So, you need to upgrade to a MATLAB version that is R2021a or higher to run the shapley command.

Thanks for your answer. I did it few month back.

If this answers your question, it is recommended to accept the answer. I'm glad to hear that you upgraded your MATLAB already.
