Why do I get an error when trying to run a simulation with a compiled simulink model?

This is the code:

        Time = (0:99999)';
        InputA = rand(100000,1); InputB = rand(100000,1); InputC = rand(100000,1);
        InputD = rand(100000,1); InputE = rand(100000,1); InputF = rand(100000,1);
        InputG = rand(100000,1); InputH = rand(100000,1); InputI = rand(100000,1);
        InputmatrixDouble = [Time InputA InputB InputC InputD InputE InputF InputG InputH InputI];
        save('InputmatrixDouble', 'InputmatrixDouble');
        [status, cmdout] = system(['Testcase_double.exe -i InputmatrixDouble.mat -tf ', num2str(Time(end)) ,' -o OutputmatrixDouble.mat'])

All inport data types of the model are set to "double", but I get the following error when trying to run the model:

        ** Starting model 'Testcase_double' @ Thu Aug 31 09:55:02 2017
        Error starting model: Data type of matrix variable from MAT-file InputmatrixDouble.mat can only be double while data type of inport 0 is not set to double.

The error message dosn't change when i set the input data type to "Inherit: Auto"

How can I get the model running?

Your InputmatrixDouble.mat needs to be a structure, inside of array, as item 2 and 3 shows in the following doc.

Step5 (2) has an example of prepare structure format https://www.mathworks.com/help/releases/R2017a/rtw/examples/using-mat-files-to-feed-data-to-inport-blocks-for-rapid-simulations.html#zmw57dd0e4160

This is one solution that would work, yes. Step 5 of the document shows 3 different formats to save an inputmatrix. I did it like format 1), so it should also work like this?!
