Optional Arguments. DIM, SEGMENT,
EXCLUSIVE
Description. Computes a segmented COUNT 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. The result is of
type default integer and of the same shape as MASK.
Result Value. Element of the result has the value
COUNT((/ /)) where is the (possibly empty) set of elements of MASK
selected to contribute to by the rules stated in
Section 7.4.5.
Example. COUNT_PREFIX( (/F,T,T,T,T/), SEGMENT=
(/F,F,F,T,T/) ) is [0 1 2 1 2].
