MATLAB: Greek characters in m-file for comments and strings

greek charactersutf-8

Hi everyone,

I used to run Matlab 2016b on a windows 10 x64 machine, English Language. I cannot recall system locale setting on that machine though.

Out of the box, if I typed any greek characters in the comments of an m-file and save it, the next time I would open it, the characters would not be recognised properly and would appear with "chinese" effect (I apologise to our Chinese friends for the improper use of the word chinese). However I remember I had found a solution (by searching online), which was quite simple and easy to follow and it worked. Too bad that I didn't right it down somewhere.

Now I have a fresh windows 10 installation and Matlab 2017, but the matlab editor cannot read the greek characters in my m.files properly. If open the files in notepad though, the greek characters are there.

Could you help me out please? It is very important for me to retrieve those scripts.

I solved my problem. Here is the solution:

Go to Control Panel -> Clock, Language and Region -> Region and change the settings for all three tabs (Formats, Location, Administrative) to "Greek"

You should review the documentation on how to write a function, since your above code is not a correctly written function. First, come up with a name for your function, e.g. myFunction. Then create a new file called myFunction.m somewhere on the MATLAB path (e.g. your working directory). Then in that file put your code. E.g.,

function result = myFunction(V)
result = V;  % <-- allocate the result variable, copying all elements
%

% Insert your code here to create the result variable from the V variable
%
return
end

I will give you some hints about correcting your code:

Change this loop:

for i=1:1:6;  % <-- hard coded for exactly 6 elements

to this

for i=1:numel(V)  % <-- allows any size input

The following test has an error in the logic (compare this carefully with the requirement):

if [V(i)<0 | mod(V(i),2)==0 | mod(V(i),4)==0]

The following line has an error on the right hand side calculation (compare this carefully with the requirement):

    V(i)=i*i;

If you don't see what the errors are, step through a small example by hand and compare that to the code result. E.g., at the command line type this:

V=[10,4,7,-8,-3,-12];
myFunction(V)

I managed to resolve this issue by renaming the file MATLABroot\bin\lcdata_utf8.xml to lcdata.xml.
