Programmatically Set Argument Field Of Simulink Parameter
显示 更早的评论
Hello,
Does anyone know how to programmatically set the argument field of a Simulink Parameter, shown in the attached image?
For context, I have a model with a large number of parameters that is used for code generation, and I want to be able to load them all into the model workspace. Have managed to get everything else configured autonomously except this argument field.
Many Thanks,
Ross

Hi Ross,
To set the ‘Argument’ property of the ‘Simulink.Parameter’ object, you can leverage the ‘set_param’ function in MATLAB. This function allows you to manage the ‘ParameterArgumentNames’ property, which takes a string of parameter names whose ‘Argument’ values should be checked.
For example, if you have two ‘Simulink.Parameter’ objects, ‘Param1’ and ‘Param2’ , you can use the following code snippet to check the 'Argument' property:
% Initializing and loading the Model named 'model_name'
load_system('model_name');
% Checking Argument for Both Param1 and Param2
set_param(model, 'ParameterArgumentNames', 'Param1,Param2');
% Checking Argument only for Param1
set_param(model, 'ParameterArgumentNames', 'Param1');
To uncheck the ‘Argument’ property for specific parameters, you can remove those parameters from the string and pass only the ones you want to keep checked.
Refer to the following example code snippet
% Unchecking Param1 and checking Param2
set_param(model, 'ParameterArgumentNames', 'Param2');
% Unchecking all parameters
set_param(model, 'ParameterArgumentNames', '');
Please refer to the following MathWorks Documentation to learn more about ‘set_param’ function in MATLAB: https://www.mathworks.com/help/releases/R2021b/simulink/slref/set_param.html
I hope this helps you in solving the issue.
