This video explains how to design a stateflow chart to calculate the sum of factorial of first N natural numbers. N is a positive integer taken as an input.

You can view below videos where it is shown how to compute just the factorial of Nth number.

Below video shows the steps to compute Factorial in MATLAB and Stateflow:

Source code:

function outputArg = Factorial_Sum(inputArg)

outputArg = 0;

for i = 1:inputArg
outputArg = outputArg + factorial(i);
end

end
