Executing MBC models that have placed in an array

I have created models in MBC Toolbox and exported them to the workspace. I then placed them in an array so that I can pass them as a single argument to a function. The problem is that I don't know how to execute the models after I have placed them in the array. From the command line, the models are executed as such:

r1 = Model1([3000, 50, 0, 14, 400, 30]); r2 = Model2([3000, 50, 0, 14, 400, 30]);

I put the models in the array as follows:

arrModels = [Model1, Model2];

I tried to execute them like this:

r1 = arrModels(1)([3000, 50, 0, 14, 400, 30]);

but that didn't work.

Any ideas?
