Hello,
I wanted to know if it was possible to do stochastic simulation with monte carlo method in Stateflow?
Thanks

Monte Carlo simulations can be performed using Stateflow charts integrated with Simulink and MATLAB. Below is a simple implementation example where a Stateflow chart accepts the output's initial value as its input and generates a step signal with a step size of 1.
In this configuration:
- A Constant block supplies the Stateflow chart input, sourcing values from workspace variable x_const
- The chart output routes to the base workspace via a To Workspace block
Following model setup, simulations can be executed from MATLAB using this script:
figure
for x_const = 1:10
simOut = sim('modelName.slx');
plot(simOut.y,'DisplayName',"Input = "+num2str(x_const))
hold on
end
hold off
The resulting figure demonstrates Monte Carlo simulation outputs:
