MATLAB Function: Exponential Calculation Using Factorial

This function computes the exponential of a given number, 'x', using the formula:

'e^x = 1 + x + (x^2)/2! + (x^3)/3! + ...'

The function starts by initializing the 'result' to 1 and the 'factorial' to 1. It then iterates from 1 to 'x', calculating the factorial and adding the term '(x^n)/factorial' to the 'result' at each iteration. Finally, it returns the computed 'result'.

function result = computeExponential(x)
    result = 1;
    factorial = 1;

    for n = 1:x
        factorial = factorial * n;
        result = result + (x^n) / factorial;
    end
end
