Can't add a Greek letter into sprinf

Hi,

I am having problem with adding \angle character into my sprintf command. The result is for command window only.

Here is the line I need to add the character to:

    out = arrayfun(@(x, y) sprintf('%f \angle %7.4f°', x, y), absA, phaseA, 'uni', 0);

Angle is not a greek character.

You are trying to use tex with command window output. That will not work. Unicode might work if you are using an appropriate font.

anglechar = char(8736);

out = arrayfun(@(x, y) sprintf('%f %s %7.4f°', anglechar, x, y), absA, phaseA, 'uni', 0);

Thanks. It had to be like below though:

      out = arrayfun(@(x, y) sprintf('%f %s %7.4f°', x, anglechar, y), absA, phaseA, 'uni', 0);

But that was the solution.

Yes, sorry about the typo.

Walter, what If I would like to writte a greek letter using sprintf()?

I'm trying:

"eq_beta = sprintf('\beta = (%.2f) e/D² + (%.2f) e/D + (%.2f)',beta_fit(1),beta_fit(2),beta_fit(3));

text(1.0,0.75,eq_beta)"

but '\beta' seems not to work.

SOLVED: Using '\\beta' works out fine! I will leave my comment here if anyone else in the future have the same question.

Thank you very much for the tip on using double-/ (//beta)

Yes thank you. Been having that problem for awhile and couldn't figure it out
