Simulink functions appear to be missing

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

>>restoredefaultpath
>>rehash toolboxcache
>>savepath

Also delete the contents of the MATLAB prefdir which can be found by typing 'prefdir'.

If none of the above works, contact MathWorks support.
