[Stephen23]

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

[Steven Lord]

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').

[Guillaume]

Because, as clearly written in the documentation, intmax with no arguments is the same as

intmax('int32')

If you want 9223372036854775807, then you need to write

intmax('int64')
