Factorial exists:
factorial(N)
But for the others use some basic code:
mod(N,2)==0 % iseven
mod(N,2)==1 % isodd
fix(N)==N % isint
Tip: learn to navigate the MATLAB documentation using the Contents (on the left-hand side of the webpage). There you can browse and find many related functions and lots of useful information. Try it! Open the page for factorial , and you can see the contents also lists similar functions: gcd, factor, lcm, etc.
