The factorial of a positive integer n is denoted n is and n! is defined as follo

Question

The factorial of a positive integer n is denoted n is and n! is defined as follows: n! = n(n - 1)(n - 2) (1) Examples: 11 = 1; 61=6 times 5 times 4 times 3 times 2 times 1 = 720 Also, by definition 0! =1 Write a MATLAB script to calculate the factorial of a user specified integer n. YOU ARE NOT ALLOWED TO USE THE BUILT-IN MATLAB FACTORIAL FUNCTION YOU ARE BEING ASKED TO WRITE YOUR OWN FACTORIAL SCRIPT Your script must use either input, disp or fprintf statements and for loops or the while construct. The syntax of the input, disp and fprintf statements is given in question 2, of this test The (basic) syntax of the for statement is: for index=l:maxindex block of statements end and the syntax of the while statement is; while (logical expression) block of statements end

Explanation / Answer

Matlab Code:

n=input('Enter the number to calculate factorial:');
fact=1;
if n==0
fact=1;
else
for i=1:n
fact=fact*i;
end
end
fprintf('Factorial of %d is:',n);
disp(fact);

Output:

Enter the number to calculate factorial:10
Factorial of 10 is: 3628800
