#Day53-Factorial of a Number
Task:

Write a code to find factorial of a  number. 
Factorial(6)
1*2*3*4*5*6
=720

Note: This code can be done using the in-built command. But for the challenge, I am trying to avoid those.
Matlab code

function factorialn = factorialofnum(n)

factorialn=1;

if n<0

disp('no factorial');

elseif n==0

disp('Factorial is 1');

else

 

for i=1:1:n

    factorialn=factorialn*i;

end

fprintf('The factorial of %d is %d',n,factorialn);

end

Sample Input and Output

>> factorialn = factorialofnum(-1)

no factorial

factorialn =

     1

>> factorialn = factorialofnum(0)

Factorial is 1

factorialn =

     1

>> factorialn = factorialofnum(6)

The factorial of 6 is 720

factorialn =

   720
