 ISINT determine if input matrix is integers

 ISINT a Matlab function to determine which input matrix positions 
       contain an integer or one that can be represented as an integer.
       ISINT returns 1 where matrix entry is integer and a 0 otherwise.

       If x is a vector or matrix, ISINT returns a vector or matrix 
       the same size as x with each element of the input being 
       evaluated as above.

       Ex. 1;  if x=3.2, ISINT returns 0
               if x=3.0, ISINT returns 1
               if x=3, ISINT returns 1
               if x=0, ISINT returns 1

       Ex. 2;  >> x=[3   3.5
                     4.5 6  ];
               >> isint(x)
                 
               ans = 1 0 
                     0 1
