Optional Arguments. DIM, MASK, SEGMENT,
EXCLUSIVE
Description. Computes a reverse, segmented SUM scan along
dimension DIM of ARRAY.
Class. Transformational function.
Arguments.
ARRAY must be of type integer, real, or complex. It must not be scalar.
DIM (optional) must be scalar and of type integer with a value in the range 1 < DIM < n, where n is the rank of ARRAY.
MASK (optional) must be of type logical and must be conformable with ARRAY.
SEGMENT (optional) must be of type logical and must have the same shape as ARRAY.
EXCLUSIVE (optional) must be of type logical and must be
scalar.
Result Type, Type Parameter, and Shape. Same as ARRAY.
Result Value. Element r of the result has the value
SUM((/ a1,...,am /)) where (a1,...,am) is the (possibly empty) set of elements of ARRAY selected
to contribute to by the rules stated in
Section 7.4.5.
Example. SUM_SUFFIX( (/1,2,3,4,5/), SEGMENT= (/F,F,F,T,T/) ) is [6 5 3 9 5].
