special symbols in figures

Thomas Clerc — Mon, 06 Aug 2007 10:11:03 -0400

I have a problem to write correctly the ylabel of a figure.
In LateX it is written:

ln((L(\alpha,\hat{\tau}_{\alpha})))

but MatLab does not interprete it and put this expression
with all the slashes and stuff.

How could I do?

Thnak you

Thomas

You need to work on your TeX code. Start by building it up. For
example,

ylabel('\alpha')
% and then try
ylabel('\alpha,{\tau}_{\alpha}')

Look here for more information on allowed TeX in MATLAB:

You may want to look at \wedge instead of \hat as well.

while on the subject, does anyone know why using a latex
interpreted text anywhere in the figure causes the exported
eps file to lose the very important bounding box
information? Thanks,

Thank you all for your help.

I tried this code:

x=1:20; plot(x,sqrt(x));
t='$ln((L(\alpha,\hat{\tau}_{\alpha})))$';
ylabel(text(.1,.5,t,'interpreter','latex'));

It gives a plot with a number as ylabel instead of the
mathematical expression I want.

Any idea how to deal with that?

must read:

ylabel(t,'interpreter','latex');
