Is there built in functions in matlab such as iseven,isint and factorial in matlab? Can any one please help?

Answer 1

[Stephen23]

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.
