I have a pre-allocated BitVector that fills randomly inside a loop. Based on that BitVector, I want to create a view of a Matrix but it allocates. Is there a workaround? A simple example: using Chairmarks ix = BitVector(zeros(10)) # values change x = rand(10, 10) # stays fixed ix .= bitrand(10) @…

Matrix view based on BitVector?
