It is straightforward to write a simple anonymous function that will return 1 (true) when those conditions are met:
int_gt_0 = @(n) (rem(n,1) == 0) & (n > 0); % Returns 1 For Integers Greater Than 0
v = [-2 -1 -0.9 0 0.9 1 2] % Test Arguments
result = int_gt_0(v) % Test The Function
produces:
v =
-2 -1 -0.9 0 0.9 1 2
result =
0 0 0 0 0 1 1
