This error might have occurred due to Improper installation of MATLAB.
In order to work around the issue, start MATLAB with 'nojvm' tag. Please follow the steps given below:
1. Open Command Prompt and navigate to the drive where you installed MATLAB.
2. Execute the following command to open MATLAB with 'nojvm' tag in Command Prompt:
matlab -nojvm
3. MATLAB Command Window will open up and then you can execute the following commands in it:
>>rehash toolboxcache
4. Restart MATLAB normally.
If the above solution does not work, try reinstalling MATLAB.
