How to create a structure which can be fed into the inport with data type Bus?

I am writing a MATLAB script which calls the Simulink function. The inport of these Simulink function are connected to the data script is generating in workspace. I am able to connect all the data type except bus data. With bus data I am getting following error. " Unsupported input format. Available formats include: (1) a double non-complex matrix, (2) a structure with or without time,(3) a MATLAB timeseries object, (4) a structure with MATLAB timeseries objects at all leaves (for bus input), (5) a Simulink.Timeseries object, (6) a Simulink.TsArray object (for bus input). All formats require the data to be finite (not Infinity or NaN)."
