Optional Arguments. `DIM`, `SEGMENT`, `EXCLUSIVE`

Description. Computes a segmented logical exclusive OR scan along
dimension `DIM` of `MASK`.

Class. Transformational function.

Arguments.

MASK must be of type logical. It must not be scalar.

DIM (optional) must be scalar and of type integer with a value in
the range ,
where is the rank of `MASK`.

SEGMENT (optional) must be of type logical and must have the same shape as
`MASK`.

EXCLUSIVE (optional) must be of type logical and must be scalar.

Result Type, Type Parameter, and Shape. Same as `MASK`.

Result Value.
Element of the result has the value `PARITY((/ /))`
where is the (possibly empty) set of elements of `MASK`
selected to contribute to by the rules stated in
Section .

Example. `PARITY_PREFIX( (/T,F,T,T,T/), SEGMENT= (/F,F,F,T,T/) )` is ,T,T,F,T,F,, plus 1filll
-1;T,T,F,T,F,; plus 1filll
-1:T,T,F,T,F,: plus 1filll
-1.T,T,F,T,F,. plus 1filll
-1T,T,F,T,F, plus 1filll-1.
