Dear All, I’m trying to call a function(.jl) in a folder. terminal reported a bug: "MethodError: no method matching getindex" Attached text you find the test code: function testc(Nx,Ny,c0) NxNy = Nx*Ny ccc=zeros(NxNy,1) for i=1:Nx for j=1:Ny ii =(i-1)*Nx + j*Ny ccc[ii] =c0 + ii*NxNy end end r…

You are using square brackets testc[Nx, Ny, c0] in calling your function when you should be using round brackets testc(Nx, Ny, c0) I seem to remember that you are transitioning from Matlab - I think you’ll find with time that this is one of the key day-to-day improvements working in Julia compared …

Hi nilshg, such results came from MATLAB to Julia translator | MATLAB to Julia converter Matlab: [out1,out2,…,outn] = functionname(arg1, arg2, …, argn) Julia: [out1,out2,…,outn] = functionname[arg1, arg2, …, argn] Many many thanks for your support! Best!

I would recommend against using any of this type of automatic conversion tool. As you can see, they don’t really work and in the end it will likely take longer time to use the tool than to do it manually. Also, if you want to program in Julia you still need to learn the language, and rewriting a pro…

I agree with @kristoffer.carlsson , although to make life easier for people who still want to use the translator I’ve filed an issue here .

The translation is fundamentally impossible because you don’t know if the symbol is a function or an array by just parsing the code.

@Tamas_Papp , I used your suggested web ( tools, eg this one , translate a subset) to test a very very simple function, previously, to apparently little effect.

Please do not misrepresent what I said — as clarified in that topic , I never suggested that you use this tool, or any other. That said, you are of course free to ignore advice from multiple experienced Julia users, but this case is a perfect demonstration of why translation tools will not help you.…

The thing is, your function has not been defined correctly, as it should be this: function testc(Nx, Ny, c0) ccc = zeros(Nx, Ny) # Erstelle ein 2D-Array mit Nx Zeilen und Ny Spalten for i = 1:Nx for j = 1:Ny ii = (i - 1) * Ny + j ccc[i, j] = c0 + ii end end return ccc end Is that what yo…

This was discussed with @Aquaman previously, to apparently little effect.
