running simulink in rapid acceleration mode within a function

Hi,

the calculation of my simulink simulation, takes about 30s in rapid acceleration mode, and about 10 min in accelaration mode. Since I need the result of the simulation to calculate gradients for fmincon, it is neccessary, that I evaluate the result of the simulation in a function. Therefore, in my function that calculates the gradients, I'm using:

options = simset('SrcWorkspace','current', 'DstWorkspace', 'current');

sim('sensitivityAnalysis',[],options);

With this, I make sure, that Simulink uses the workspace of the function and not the global workspace.

Unfortunately, 'DstWorkspace' is not supported in rapid acceleration mode.

Is there any alternative?

At the moment, I have absolutely no idea, how to use the rapid accelerator mode for calculating the gradients in a way, that works with fmincon.

Thanks, Arco

I think, I found something, that does the job: http://www.mathworks.de/de/help/simulink/examples/parallel-simulations-using-parfor-parameter-sweep-in-rapid-accelerator-mode.html
