The intmax help states " intmax('int32') is the same as intmax with no arguments."

I understand why you're confused. Whether MATLAB is a 32-bit or a 64-bit application does not change what intmax returns. You can ask for intmax of any of the eight integer types regardless of whether you're running a 32-bit version of MATLAB or a 64-bit version of MATLAB. As Stephen and Guillaume have said, intmax is equivalent to intmax('int32').
