The factorial of a positive integer n is denoted n! and is defined as follows: n! = n(n - 1)(n - 2)... (1). Examples: 1! = 1; 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720. Also, by definition 0! =1. Write a MATLAB script to calculate the factorial of a user specified integer n. 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 = 1: maxindex block of statements end and the syntax of the while statement is: while (logical expression) block of statements end
