Question

Special Problem: Automated Factorial

Create a MATLAB function called xfact that uses a loop to calculate the factorial of an integer. Your function should take a single integer input. Your function should compute the factorials of every integer from 1 to the integer provided by the input. Test your function by prompting the user to enter an integer N and, using a loop create an array named X of length N that contains the factorials of the numbers 1 to N. That is, X(1) = 1!, X(2) = 2!, X(3) = 3! … X(N) = N!

Answer 1

function result = xfact(n)
    if n == 0
        result = 1;
    else
        result = n*xfact(n-1);
    end
end

N = input("Enter a value for n: ");
X = [];
for i=1:N
    X(i) = xfact(i);
end
X
