In Julia, this is better done with a list comprehension altogether, eliminating the need for allocating X and Y: Z = Usually something along the lines of X, Y = meshgrid(xs, ys) However, most of the uses of meshgrid in MATLAB is for stuff where you want to do a bunch of calculations for each point on a grid, and where each calculation is dependent on the coordinates of just one point. (If youвЂ™re not happy with the orientation of the axes, just switch i and j in the meshgrid implementation.) Try it out with X, Y = meshgrid(1:15, 1:8). Mind you, this is not the most performant way to do this! meshgrid(xs, ys) = for i in 1:length(xs), j in length(ys)], for i in 1:length(xs), j in 1:length(ys)] Making do without meshgrid (and getting out ahead!)ДЇor starters, if what you are after is a straight-up port, meshgrid is very easy to implement for yourself, so that you donвЂ™t have to think about the rest.

As a user looking for a meshgrid function, where did you look? What did you look for, more specifically? Would it have helped to have some examples along the lines of вЂњwhen you want to do this, using meshgrid, in MATLAB, hereвЂ™s how to do the same thing without meshgrid in JuliaвЂќ? I could turn the following writeup into a FAQ entry or something, but it would be nice to know where to place it to actually have it make a difference. Since this question is recurring, I think the problem might rather be documentation. Instead of implementing it and keeping with inefficient habits, embrace the fact that there are better ways to do things :) The thing with meshgrid, is that itвЂ™s terribly inefficient compared to the equivalent idioms in Julia.
