ISINTTYPE ISINTTYPE Test For Integer-type Array

Usage

The syntax for isinttype is 

   x = isinttype(y)

and it returns a logical 1 if the argument is an integer type
and a logical 0 otherwise.  Note that this function only tests
the type of the variable, not the value.  So if, for example,
y is a float array containing all integer values, it will
still return a logical 0.
