How do I create a Simulink model from the MATLAB command line?

I need to create a Simulink model using MATLAB commands or scripts. What functions and/or utilities are available to enable me to do this?

You can create a Simulink model and add blocks/ lines to it using 'add_block' and 'add_line' commands. For example to add a Constant block which provides an input to the To Workspace block to a blank model, you can use the following MATLAB code:

mdl='myModel';  % this is a blank model at first
load_system(mdl);  

add_block('built-in/Constant',[mdl '/Constant'])
add_block('built-in/To Workspace',[mdl '/Output'],'Saveformat','Array',...'SampleTime','-1','VariableName','sim_out','MaxDataPoints','1');

add_line(mdl,'Constant/1','Output/1','autorouting','on');

For more information on 'add_block', please run the following command in the command window of MATLAB R2020b to access the release-specific documentation:

>> web(fullfile(docroot, 'simulink/slref/add_block.html'))

Additionally, for more information regarding 'add_line', you can use the command below:

>> web(fullfile(docroot, 'simulink/slref/add_line.html'))

An overarching documentation page regarding Simulink blocks, which includes modifying the parameters programmatically with 'get_param' and 'set_param', can be accessed by running the following command:

>> web(fullfile(docroot, 'simulink/blocks.html'))
