Any Reduction — nv_reduce_any • anvl

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

Usage

nv_reduce_any(operand, dims = NULL, drop = TRUE)

Arguments

operand: (arrayish)
Operand.
dims: (integer() | NULL)
Dimensions to reduce. If NULL (default), reduces over all dimensions, returning a scalar.
drop: (logical(1))
Whether to drop reduced dimensions.

Value

arrayish
Boolean array. When drop = TRUE, the reduced dimensions are removed. When drop = FALSE, the reduced dimensions 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 dims -> scalar
#> AnvlArray
#>  1
#> [ CPUbool{} ] 
nv_reduce_any(x, dims = 1L)
#> AnvlArray
#>  1
#>  1
#> [ CPUbool{2} ]
