COUNT_SCATTER(MASK,BASE,INDX1, ..., INDXn)

Description. Scatters elements of MASK to positions of the result indicated by index arrays INDX1, ..., INDXn. Each element of the result is the sum of the corresponding element of BASE and the number of true elements of MASK scattered to that position.

Class. Transformational function.

Arguments.

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

BASE must be of type integer. It must not be scalar.

INDX1,...,INDXn must be of type integer and conformable with MASK. The number of INDX arguments must be equal to the rank of BASE.

Result Type, Type Parameter, and Shape. Same as BASE.

Result Value. The element of the result corresponding to the element of BASE has the value + COUNT( (//) ), where () are the elements of MASK associated with as described in Section 7.4.4.

Example. COUNT_SCATTER((/T, T, T, F/),(/1, -1, 0/),(/1, 1, 2, 2/)) is [3 0 0].
