Re: [julia-users] Meshgrid function

Julia devs are working hard trying to make a language than is consistent and elegant, they don't want to add functions in Base only because they are convenient for people coming from a particular background when there's a more "Julian" way of doing it. Plus if you start adding matlab's

" and as long as it’s not in Base there’s a good chance that beginner Julians will pick up more performant idioms." Hi Tomas, I think this is a big mistake so many Julia developers (not all) are making: Julia should not just be great for performance of code but also for performance of the

Re: [julia-users] Meshgrid function

I also don't see the major issue with the inefficiency of meshgrid. We do provide functions for evaluating c = a * b with a, b being vectors and we know that it is not efficient to do so (due to the temporary vector introduced) Tobi Am Mittwoch, 9. März 2016 10:54:18 UTC+1 schrieb Christoph

Re: [julia-users] Meshgrid function

Nice list of alternatives. But it doesn't change the fact that meshgrid is very easy to use, and very easy to read. New idioms should not be forced on developers. I know in what ways mesh grid is inefficient and when that matters then I won't use it. But more often than not I just want a

Re: [julia-users] Meshgrid function

Neat. Wherever it goes it needs a pointer from http://docs.julialang.org/en/latest/manual/noteworthy-differences/#noteworthy-differences-from-matlab but its a bit long to actually go there. On Tuesday, 8 March 2016 17:00:53 UTC+10, Tomas Lycken wrote: > > The thing with meshgrid, is that

Re: [julia-users] Meshgrid function

That's awesome Tomas. Thanks for the lesson :D

Re: [julia-users] Meshgrid function

The thing with meshgrid, is that it’s terribly inefficient compared to the equivalent idioms in Julia. Instead of implementing it and keeping with inefficient habits, embrace the fact that there are better ways to do things :) Since this question is recurring, I think the problem might

Re: [julia-users] Meshgrid function

Try Ainterp = [itp[x,y] for x in X, y in Y] It's best to do this inside a function, because then the element type should be inferred, and it will be far more efficient. Best, --Tim On Sunday, March 06, 2016 05:22:17 PM mauricio...@gmail.com wrote: > Thank you for your note, > > But the

I used the meshgrid in Julia's examples folder: https://github.com/JuliaLang/julia/blob/master/examples/ndgrid.jl On Sunday, March 6, 2016 at 8:33:58 PM UTC-5, Isaiah wrote: > > I think most pure-Julia interpolation work has converged to the > Interpolations package:

I think most pure-Julia interpolation work has converged to the Interpolations package: https://github.com/tlycken/Interpolations.jl (several alternatives are also listed on that page) On Sun, Mar 6, 2016 at 8:22 PM, wrote: > Thank you for your note, > > But the problem

Re: [julia-users] Meshgrid function

Thank you for your note, But the problem is that broadcasting will not work in my case, once I already have the three vectors that I want to plot instead of two entries and one image (as in the example). I believe that I need something to interpolate my vectors in order to generate the

[julia-users] Meshgrid function

Is the meshgrid function (similar to MATLAB) available in Julia? I'm trying to plot a surface using 3 (1D) vectors and I'm not sure yet how can I deal with this problem without using this function. Thank you!
