Display µm not correct in figure in Matlab

I use Matlab 2011b

I have code for figure like this:

...

set(0,'DefaultAxesFontName', 'Times New Roman')
set(0,'DefaultAxesFontSize', 12)
plot(x1,y1,'r',x2,y2,'MarkerEdgeColor','b')
xlabel('Zsnsr [µm]') %Display not correct
ylabel('DeflV')
set(gca,'XDir','reverse')
axis([xmin xmax ymin ymax])

(end)

....

and the figure Matlab draw like this picture (red line) I don't know why and how to solve this.

Thanks!

The xlabel documentation explains this under "Interpretation of text characters".

[Ilham Hardy]

Try this,

xlabel('Zsnsr [\mum]','interpreter','Tex')

It is Ok. Thank!

But can you explain why it look that?

And what does "[\mum]','interpreter','Tex'" mean?

Thanks!

But can you explain why it look that?

If you referering to the red line, it is obvious that your x1 and y1 data produce the red line plot (ergo, plot(x1,y1,'r'.. ). The 'r' means you want to plot the x1 and y1 in red color.

And what does "[\mum]','interpreter','Tex'" mean?

Tex is text-interpreter used widely to express symbols (e.g. mathematical symbol). The text to be interpret by the Tex (or LaTex) usually preceded with a backslash (\), in this case (\mu) is merely a command to write micron/mu label. Ergo '\mum' will create 'µm' label.

Hope this helps,

how to write m() in matlab kindly send me the coding for this

[Walter Roberson]

title('\mu', 'interpreter', 'tex')
xlabel('$\mu$', 'interpreter', 'latex')
ylabel('μ', 'interpreter', 'none')
text(0.5, 0.5, 'μ', 'interpreter', 'tex')

However you cannot use 'μ' with interpreter latex, and when you use interpreter latex you need the dollar signs.
