Simulink functions appear to be missing

13 views (last 30 days)
Hello everybody,
I am having a real weird issue when I start up simulink. I get two error mesages:
  1. Unrecognized function or variable 'start_simulink'
  2. The Matlab Path must have these directories for Simulink to function: toolbox/simulink/cre/api Matlab cannot continue. Please rstore the path and restart Matlab
Additionally, when I try to make a project I get the error message:
  • Undefined function 'simulink_version' for input arguments of type 'char'
If I try to open up an example I get the error:
  • Undefined function 'bdlsLoaded' for input of type 'char'
I've looked all over for an answer but can't seem to fix this issue.

This could be a license checkout issue. Execute the following command to see if it gives an output of 1.
>> license('checkout','SIMULINK')
Or there may have been changes to the MATLAB path or settings. To restore the default path and clear cache, run the following commands in the command line
>>rehash toolboxcache
Also delete the contents of the MATLAB prefdir which can be found by typing 'prefdir'.
If none of the above works, contact MathWorks support.
