MATLAB: Get and set Simulink model data from Matlab

modelsimulink

I have a simple model with 1 input and output. The input it directly linked to the output. I was wondering if there was any way I could get the input name, set a value to it, run it and see if the output matches the input. I want to try and do this from an .M file if possible. Thanks!

Perhaps this explanation of the get_param and set_param commands will help. You could use get_param and set_param from within a mfile that uses the sim command to run the simulation. If your input and output are scalars, just take their difference in the mfile after the sim command. If they are time series,

isDifferent = sum(myInput - myOutput) ~= 0 ;

Use set_param() on the appropriate blocks of the model to change the configuration of the model, and then sim() the model and record the results. For example,

gains = [1/10 1 2 5 10 50 100];
ngains = length(gains);
results = cell(ngains,1);
model_name = 'vdp';
block_name = 'vdp/Mu';
for K = 1 : ngains
    set_param(block_name, 'Gain', sprintf('%f', gains(K)));
    results{K} = sim(model_name);
end

There is a block parameter 'Commented' you can use with SET_PARAM and GET_PARAM commands. Example

Open the vdp demo:

vdp

Select the gain block called 'Mu'
Try commands:

get_param(gcb,'Commented')
set_param(gcb,'Commented','on')
set_param(gcb,'Commented','off')
