I already tried, but nothing changed

Ohh, If changing the icon by selecting "matlab.ico" file did not work for you. I will suggest re-installing the MATLAB.

Thanks, I fix this problem just now. I stop the windows explorer, and use cmd to delete the IconCache.db, after those step, restart windows explorer. Then the matlab icon comebacks to the taskbar.
