How do I programmatically set the Argument checkbox of a model workspace variable?
显示 更早的评论
I'm assigning some variables to a model workspace programmatically and I'm planning on programmatically creating a mask to tune them. I can't figure out how to check the Argument checkbox (programmatically) so that the model mask will be able to use them.

To set arguments programmatically, use "set_param" with the model parameter "ParameterArgumentNames". This parameter is a comma-separated string with the names of parameters in the model workspace. For example, if "Ts", "config", and "tunable" are parameters in the model workspace, the below MATLAB code sets them to model arguments:
% Argument checkbox will be checked for the Simulink.Parameter objects Ts,config and tunable
set_param(bdroot,'ParameterArgumentNames','Ts,config,tunable');
To uncheck the Argument checkbox for a parameter, set "ParameterArgumentNames" without that parameter's name in the comma-separated string:
% Argument checkbox for the variable Ts will be unchecked
set_param(bdroot,'ParameterArgumentNames','config,tunable')
See the MATLAB example "Parameterize a Referenced Model Programmatically" for another example of using "ParameterArgumentNames":
