I made a simulink model and linked it with interpreted matlab function block which has my .m code file, but I need 6 inputs to the .m file that are supposed to come from my model. What function do I use in my .m file to get values from my simulink model. As the interpreted function block has only one input, I have used a MUX.

Hello Prerna,

The output of a 'MUX' is a vector, allowing the elements within the output signal to be indexed like any other vector elements. To demonstrate this, consider the following example: Six 'Constant'blocks are created and connected to a 'MUX'. The output from the 'MUX' is then directed to an 'Interpreted MATLAB Function Block'.

The 'Interpreted MATLAB Function Block' extracts each input and calculates their sum, which is then displayed in the 'Display' Block. Below is the code used within the 'Interpreted MATLAB Function Block'.

function output = mFileFromMATLAB(inputVector)
    % Extract each input from the vector
    input1 = inputVector(1);
    input2 = inputVector(2);
    input3 = inputVector(3);
    input4 = inputVector(4);
    input5 = inputVector(5);
    input6 = inputVector(6);
    
    output = input1 + input2 + input3 + input4 + input5 + input6;
end
