Hi, I have problem with isinteger() function. I wrote following function:

function [x] = f1(n)
b=ininteger(n);
end

This is a partial code. I want to accept integer n to function f1. Whenever user inputs integers, such as 3 or 4, b = 0 as Matlab treats constants as double. I tried converting n to int8(), but then floating value also gets converted to integer. How to test whether input constant is an integer or not? Thanks.
