Why does not Simulink work with timeseries input?

I have created a timeseries object from an array with "init=timeseries(falk);" function. I set this "init" timeseries as an input file of a simulink modell in simulation parameters, and but it doesn't work because of this: "Unsupported input format. The input data must be either a double non-complex matrix with finite elements, a structure, a Simulink.Timeseries object, or a Simulink.TsArray object". So I think I have to create a Simulink.Timeseries object from my array. How can I do that?
