Any Reduction

Performs logical OR along the specified axes. Returns TRUE if any element is TRUE.

Usage

nv_reduce_any(x, axes = NULL, drop = TRUE)

Arguments

x

(arrayish)
Input array.

axes

(integer() | NULL)
Axes to reduce. Negative values count from the end, i.e. -1 refers to the last axis. If NULL (default), reduces over all axes, returning a scalar.

drop

(logical(1))
Whether to drop reduced axes.

Value

arrayish
Boolean array. When drop = TRUE, the reduced axes are removed. When drop = FALSE, the reduced axes are set to 1.

See also

prim_reduce_any() for the underlying primitive.

Examples

x <- nv_matrix(c(TRUE, FALSE, TRUE, TRUE), nrow = 2)
nv_reduce_any(x)            # all axes -> scalar
#> AnvlArray
#>  1
#> [ CPUbool{} ] 
nv_reduce_any(x, axes = 1L)
#> AnvlArray
#>  1
#>  1
#> [ CPUbool{2} ]
