The factorial of n is defined as n!=1×2×3×···×n. Write a Matlab.m function myfactorial to compute factorials in a recursive manner by calling the m-function myfactorial itself. Test your m-function myfactorial forn = 0,1,2,3,4,5,6,7,8,9,10.

Answer #1

MATLAB Script:

close all
clear
clc

for n = 0:1:10
fprintf('myfactorial(n = %2d) = %d\n', n, myfactorial(n))
end

function f = myfactorial(n)
if n == 0
f = 1;
return
end
f = n * myfactorial(n - 1);
end

Output:

myfactorial(n = 0) = 1
myfactorial(n = 1) = 1
myfactorial(n = 2) = 2
myfactorial(n = 3) = 6
myfactorial(n = 4) = 24
myfactorial(n = 5) = 120
myfactorial(n = 6) = 720
myfactorial(n = 7) = 5040
myfactorial(n = 8) = 40320
myfactorial(n = 9) = 362880
myfactorial(n = 10) = 3628800

Write Java program Lab42.java which takes as input two positive integers m and n and computes their least common multiple by calling method lcm(m,n), which in turn calls recursive method gcd(m,n) computing the greatest common divisor of m and n. Recall, that lcm(m,n) can be defined as quotient of m * n and gcd(m,n).
