bitpack
bitpack(A::AbstractArray{T,N}) -> BitArray
Converts a numeric array to a packed boolean array
Examples
Example: Converting a numeric array to a packed boolean array
julia> A = [1, 0, 1, 1, 0, 1, 0, 0];
julia> bitpack(A)
BitArray{1}:
0x8DIn this example, the numeric array A is converted to a packed boolean array using the bitpack function. The resulting BitArray represents the packed boolean values of A.
Common mistake example:
julia> A = [1, 2, 3];
julia> bitpack(A)
ERROR: MethodError: no method matching bitpack(::Array{Int64,1})In this example, the bitpack function is applied to a non-boolean array. It's important to ensure that the input array contains only numeric values of 0 and 1 for the bitpack function to work correctly.
