The In1 block outputs a double,In2andIn3每个输出nonvirtual总线,andIn4outputs anint16.

mdl ='ex_dataset_for_inports'; open_system(mdl)

Create aDatasetobject for the root-levelInportblocks.

ds = createInputDataset(mdl)

ds = Simulink.SimulationData.Dataset '' with 4 elements Name BlockPath ____ _________ 1 [1x1 timeseries] In1 '' 2 [1x1 struct ] In2 '' 3 [1x1 struct ] In3 '' 4 [1x1 timeseries] In4 '' - Use braces { } to access, modify, or add elements using index.

Replace the placeholder value for the first signal in theDatasetwith actual signal values that you want to load into the model.

ds{1} = ds{1}.delsample('Index',[1,2]); ds{1} = ds{1}.addsample('time',[1 3 3 10]','data',[1 1 5 5]');

Examine theIn2signal.

ds{2}

ans = struct with fields: a: [1x1 timeseries] b: [1x1 timeseries]

ForIn2, create data for bus elementsaandb.

ds{2}.a = ds{2}.a.delsample('Index',[1,2]); ds{2}.a = addsample(ds{2}.a,'time',[1:10]','data',[1:10]'); ds{2}.b = timeseries((1:10)',0.1:.1:1,'Name','sig2_b');

ForIn3, specify data for elementaof the bus, and use ground values for elementb.

ds{3}.a = timeseries((1:10)',0.1:.1:1,'Name','sig3_a');

Plotds.

plot(ds)

Set theInputconfiguration parameter tods. Alternatively, you can use the Root Inport Mapper tool to set theInputparameter.

set_param(mdl,'LoadExternalInput','on'); set_param(mdl,'ExternalInput','ds');

Run the simulation. TheInportblocks use the signal data specified indsor ground values for elements that do not have specified signal data.
