I'm building a simulink model with multiple matlab function blocks( http://in.mathworks.com/help/simulink/slref/matlabfunction.html ). Each of these function blocks have a lot of constants, for example (g=9.8), common between them. I want to initialize all of these constants in one go so that I don't have to do so in each function block.

I tried initialising all the variables in matlab workspace, but they don't seem to be working.

What is the best and easiest way to go forward with this?

Adding Data to a MATLAB Function Block

Not exactly what I want. I want all my parameters to be initialized by using a .m file. How can I get all of these data from the matlab workspace to the matlab function block workspaces in simulink?

Did you ever figure this out? I'm also trying to get global data into multiple matlab function blocks inside a model. In my case, I want to have each of the function blocks update the same figure, and I'm trying to pass the figure handle.
