MATLAB: Doesn’t the Simulink model show up upon double clicking from a saved folder after it automatically starts a MATLAB session

Question

I have a problem in opening a Simulink model by double clicking it from its residing folder. In my workflow, I would like to double click the Simulink model of choice in a particular directory and expect it to:

a. Open up MATLAB

b. Open the model

As explained above, I am not able to see a Simulink model open up upon double click. Instead, only MATLAB version R2XXX a/b/SP1 opens by loading the directory where the model is located to the current working directory.

Answer 1

This behavior occurs when the file associations of type.MDL (that represent the Simulink models) have messed up their file associations. You can reset them by clicking on the link labled:

"Run utility to associate files with .mdl extension with MATLAB" at the following URL:

http://www.mathworks.com/help/releases/R2011a/techdoc/matlab_env/f8-8880.html#f8-28791

However, you need to open that link in the help browser to use this, and the MATLAB session needs to be running as an administrator.
