Unexpected result of boolean operation between vectors

[gnilrets]

vtrue = Daru::Vector.new([true]*2)
vfalse = Daru::Vector.new([false]*2)

bool = (vfalse and vtrue)

The result is a vector where all of the elements are true, where I would expect all of them to be false.

The and clause you're using is Ruby boolean and, which cannot be modified. Moreover such piecewise boolean operations aren't currently supported on Vector. Use a Daru::Core::Query::BoolArray for that.

Or alternatively:

vtrue = Daru::Vector.new([true]*2)
vfalse = Daru::Vector.new([false]*2)

bool = (vfalse.eq(false).and(vtrue.eq(true)))
# OR
bool = (vfalse.eq(false) & vtrue.eq(true))

This operation will return a BoolArray.

Thanks, this works
