Using LaTeX on matlab

Using LaTeX on matlab

Using LaTeX on matlab

(OP)
Hi people!!!

Can anyone tell me how to make a xlabel for a figure using LaTeX properties? I want that the xlabel is equal to the greek letter overline alpha.
I've tried something like that:
xlabel({text('interpreter','latex','string',['$\overline {\alpha}$'])})

but it didn't worked out.

Any ideas?

Regards

RE: Using LaTeX on matlab

Yes, for a reason I don't understand more than you do, xlabel doesn't accept all latex commands, even if you write it as you did. My solution was to rewrite the xlabel function where it simply writes a text at the correct place. Below is the program, it's kind of brute force but it works. All the if conditions are to remove the previous label if there is one. The bottom lines after the last "end" are actually the creation of the label.

ttt give you the handle to the label and sss in the character string you want as label. Write it in standart latex, including $ for math format.

You can write the same one for ylabel. You just have to add a 90 degrees rotation to the text.

function ttt=myxlabel(sss)
xlabel(' ')
aa=get(gca,'Children');
if length(aa)==1
    if(length(get(aa,'Type'))==4)
        if get(aa,'Type')=='text'
            ee=get(aa,'Extent');
            if ee(2)<0
                delete(aa)
            end
        end
    end
else
    for k=1:length(aa)
        if(length(get(aa(k),'Type'))==4)
            if get(aa(k),'Type')=='text'
                ee=get(aa(k),'Extent');
                if ee(2)<0
                    delete(aa(k))
                end
            end
        end
    end
end
ttt=text('Units','normalized','Interpreter','latex','FontSize',20,'fontweight','bold','String',[sss],'Position',[0.5,0],'HorizontalAlignment','center','VerticalAlignment','middle');
set(ttt,'units','Centimeters')
bb=get(ttt,'position');
set(ttt,'position',[bb(1) -1.1])

RE: Using LaTeX on matlab

Don't make it so hard:

xlabel('$\bar a = 17$','interpreter','latex');
