bitunpack

bitunpack(B::BitArray{N}) -> Array{Bool,N}

Converts a packed boolean array to an array of booleans

Examples

1. Unpack a packed boolean array:

   julia> packed = BitArray([1, 0, 1, 1, 0, 1]);
   julia> bitunpack(packed)
   6-element BitArray{1}:
   true
   false
   true
   true
   false
   true

   This example unpacks the packed boolean array packed into an array of booleans.

2. Convert a larger packed boolean array:

   julia> packed = BitArray([1, 0, 1, 0, 0, 1, 1, 0, 1, 1]);
   julia> bitunpack(packed)
   10-element BitArray{1}:
   true
   false
   true
   false
   false
   true
   true
   false
   true
   true

   It converts a larger packed boolean array to an array of booleans.

3. Handle empty packed arrays:

   julia> packed = BitArray([]);
   julia> bitunpack(packed)
   0-element BitArray{1}

   It correctly handles the case when the packed boolean array is empty.

Common mistake example:

julia> packed = [1, 0, 1, 1, 0, 1];
julia> bitunpack(packed)
ERROR: MethodError: no method matching bitunpack(::Array{Int64,1})

In this example, the input provided is not a BitArray but a regular array of integers. It's important to ensure that the input is a BitArray before using the bitunpack function.
