setExternalInput "The number of external inputs must be equal to the number of root-level input port blocks"

Hello

I've created a simple model for the purposes of exploring "setExternalInput." The model is called "jordanTest" as shown below. After I've set the external input and run the correspondingly modified model, I get the error below; I've compared my model's settings with those of the example from setExternalInput's documentation and they seem to be the same.

"The number of external inputs must be equal to the number of root-level input port blocks. Root-level input port blocks

include Enable blocks and Trigger blocks with 'Trigger type' set to rising, falling, or either. The model contains 3

root-level input port blocks, but 1 external inputs were specified in Configuration Parameters -> Data Import/Export ->

Input."

The error occurs after executing the last line of this code:

 t=[0:1:3];
  ds{1}=timeseries([1,1,1,1],t);
   ds{2}=timeseries([1,2,3,5],t);
   ds{3}=timeseries([6,7,4,2],t);
   in = Simulink.SimulationInput('jordanTest');
   in = in.setExternalInput(ds);
   out=sim(in)

I worked around this problem by doing the following:

    t=[0:1:3];
    mdl='jordanTest'
    inports=createInputDataset(mdl);
    
inports{1}=timeseries([5,6,4,5],[0,1,2,3],'Name',inports{1}.Name);
inports{2}=timeseries([2,4,3,6],[0,1,2,3],'Name',inports{2}.Name);
inports{3}=timeseries([1,4,2,5],[0,1,2,3],'Name',inports{3}.Name);

    in = Simulink.SimulationInput('jordanTest');
    set_param(mdl,'LoadExternalInput','on');
    in = in.setExternalInput(inports);
    out=sim(in)

It seems as if the timeseries have to have the associated port names included.
