Hello,

I am using Simulink.SimulationData.Dataset to feed a signal builder. I have a script that analyse differerences between inputs of my model and datasets stored in .mat in order to have the same amount and same names between model and scenarios defined in thoses .mat.

If I add a new input in my model, it is easy to add an element in my dataset

diff = setdiff(modelInputNames,inputNames); % modelInputNames is the input list in model,  inputNames is the input list in .mat
if ~isempty(diff)
    for j = 1 : length (diff)
        zeroInput = timeseries(0,ds{1}.Time);   %Creating an Input with zeros, to be modified with signal builder UI
        ds = ds.addElement(zeroInput,char(diff(j)));
    end
end

But if I supress an input in the model, I can't find a way to delete an Element in 'ds'.

diff = setdiff(inputNames,modelInputNames); % modelInputNames is the input list in model,  inputNames is the input list in .mat
if ~isempty(diff)
    for j = 1 : length (diff)
        %Something to delete the element diff(j) in ds
    end
end
