Dear all, I have a very basic (maybe stupid) question. I need to evaluate a piecewise function many times. My naive approach is to do something like: function myPiecewise(a,b) if a < 0 return 0.5*a + b else return - 2.5*a + b end end Is that an efficient way of implementing piecewis…

I would think that your implementation is fast. After all, it is only a single branch and should only take a few nanoseconds to run. Unless this is a serious performance bottleneck (which I doubt) I wouldn’t care about optimising it (if possible). FWIW: julia> @btime myPiecewise($(Ref(1))[],$(Ref(…
