Query or set the internal variable that controls whether non-integer ranges are allowed as indices.
This might be useful for MATLAB compatibility; however, it is still not entirely compatible because MATLAB treats the range expression differently in different contexts.
When called from inside a function with the "local"
option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
