Hello,

I have some software that uses the class RTW.TargetPrefs. This class was available up to R2012a. There is a patch available to add this class to newer releases (<http://www.mathworks.com/support/bugreports/877463)>. Basically, this patch copies some files to toolbox\rtw\rtw\@RTW\@TargetPrefs.

Unfortunately, Matlab needs a restart to find this new class. I tried rehash with different parameters to force Matlab to check for new classes, but without any success. I want to install the patch in a kind of install script and want to avoid that a user has to restart Matlab in order to get the classes. Therefore, I am looking for a way to force Matlab to check for new classes. Is there anything I can use?

Thank you,

Christian

I realized that this problem only occurs in Matlab 2014a. In Matlab 2013b and older, the new class is immediately found after a rehash, without restarting Matlab. Was the rehash command changed in Matlab 2014?
