This is a question about how to use the dot-syntax for in-place assignment for sub-arrays. Let v = [1., 2., 3., 4., 5., 6.]. I want to apply sin(...) in place to some elements. Specifically, I want to do: v[1:3] .= sin.(v[1:3]) Is this efficient? I fear we might be creating a temporary sub-array…

Is v[1:3] .= sin.(v[1:3]) efficient?

Is is unlikely. With the new @views macro it feels sufficiently easy to make everything views anyway.
