Select elements based on a conditional array.
Creates a new array that is composed of values either from array a
or array b
, based on a third conditional array. For all non-zero elements in the conditional array, the output array will contain values from a
. Otherwise the output will contain values from b
.
is equivalent to:
The conditional array must be a b8 typed array.
The select function can perform batched operations based on the size of each of the inputs. The following table describes the input and output sizes for supported batched configurations.
Output | Condition Array | Array A | Array B |
---|---|---|---|
(M, N) | (M, 1) | (M, 1) | (M, N) |
(M, N) | (M, 1) | (M, N) | (M, 1) |
(M, N) | (M, 1) | (M, N) | (M, N) |
(M, N) | (M, N) | (M, 1) | (M, N) |
(M, N) | (M, N) | (M, 1) | (M, N) |
