Use MAT-Files to Save a SimState for Future Use

To save a SimState from the MATLAB base workspace, save the variable with final state data in a MAT-file.

For example, type at the command prompt:

save('sf_car_ctx01.mat', 'sf_car_ctx01')

For more information, see save in the MATLAB documentation.

Use Scripts to Save SimState Commands for Future Use

To save a list of SimState commands for future use, copy them from a procedure and paste them in a MATLAB script.

For example, to reuse the commands in Dividing a Long Simulation into Segments, you can store them in a script named sf_boiler_simstate_commands.m:

% Load the model.
sf_boiler;

% Set parameters to save the SimState at the desired time.
set_param('sf_boiler','SaveFinalState','on','FinalStateName',...
['sf_boiler_ctx01'],'SaveCompleteFinalSimState','on');

% Specify the start and stop times for the simulation segment.
set_param('sf_boiler','StartTime','0','StopTime','400');

% Simulate the model.
sim('sf_boiler');

% Disable saving of the SimState to avoid overwriting.
set_param('sf_boiler','SaveCompleteFinalSimState','off', ...
'SaveFinalState','off');

% Load the SimState.
set_param('sf_boiler', 'LoadInitialState', 'on', ...
'InitialState', ['sf_boiler_ctx01']);

% Specify the new stop time for the simulation segment.
set_param('sf_boiler','StopTime','600');

% Simulate the model.
sim('sf_boiler');
