Say I have one column vector
n elements in it, and one row vector
m elements in it.
If I want to zip the broadcast of these two vectors,
zip(x .+ 0*y, 0*x .+ y), can I do it without generating these temporary
n × m arrays?
Can I create
z without creating
x = rand(3)' y = rand(5) tempx = x .+ 0*y tempy = 0*x .+ y z = zip(tempx, tempy)
