Special Characters App Designer

Hi everyone,

I would like to make a formula appear on my app designed with App Designer:

h(f) = h0*(3.5+f)^{\α}

I tried to type it as ( following the documentation: https://it.mathworks.com/help/matlab/creating_plots/greek-letters-and-special-characters-in-graph-text.html):

a = 'h(f) = h_{0}*(3.5+f)^{\alpha}';

app.EditField.Text = a;

But it keeps displaying it the exact same way I've written it down, no special characters are shown.

Am I doing it wrong or is this feature not supported within the app.EditField objects?

Thanks in advance!

Edit Fields cannot support tex or latex: they are input areas and supporting that possibility would require supporting a latex formula editor.

TextArea could in theory support tex or latex.... but they do not.

You can have a TextArea or EditField display literally

h(f) = h0*(3.5+f)^α

as they support unicode characters -- but the α would not be raised.

Hi Walter,

Thanks for your help.

I just discovered contacting Mathworks staff the workaround! If I write in the StartUp fcn:

app.LabelFormula.Interpreter = 'tex';

app.LabelFormula.Text = 'h(f) = h_{0}*(3.5+f)^α';

then it shows it as a formula with apix and pedix

[Walter Roberson]

what kind of component is app.LabelFormula ?

Label, sorry I put the name I gave it. And it works for Edit Fields as well

Could you confirm that you have a uieditfield and that you are able to set an Interpreter property for it? Interpreter is not a documented property for uieditfield
