LaTex for Titles in Appdesigner now possible?

I'm now finding into appdesigner myself and have saw multiple people asking how to incorporate LaTex.

There are some workaround like

text(app.UIAxes,200,1.2,'Plot of','Interpreter','latex')

but using this as title is hard to align so I strive for an inbuilt adaption, resolving this issue.

Also, I want to update the title dependent on user input. How am I supposed to do that? The plain solution I've found is by:

app.UIAxes.Title.String = "Plot of "+ double(app.CEditField.Value) + "*sin(" + double(app.mEditField.Value) + "*x)"

Can't it be shorter? Also it lacks the primordial desire to choose LaTex interpreter.

The easiest way to set the interpreter to LaTeX for a title is to use the 'interpreter' name-value pair.

title(app.UIAxes,'title string','Interpreter','latex')

However, there is no LaTeX markup in your title string, so it will still just display as text. What is the LaTeX expression you are wanting to create?

Oh, that's great to know using title instead of text so position specification is not needed. I want to have in the title but C and m should be updated (dependent on app.CEditField.Value and app.mEditField.Value) How do I tell MatLab to not interpretate these words as text?

You can refer to the 'Latex markup' description under the 'Interpreter' help section linked to above, but the short answers is to place the expression between dollar signs ($). If you use one, the output is inline. If you use 2, it is not (depends on what elements your string contains if the display is different).

title('$$C sin(m x)$$','Interpreter','latex')

I've accepted this answere even though

C = app.CEditField.Value 
m = app.mEditField.Value

are not updated when choosing different values in the Edit Field.

I tried using

title(app.UIAxes,'$$C\,\sin(m\,x)$$','Interpreter','latex')
%and
title(app.UIAxes,'$C\,\sin(m\,x)$','Interpreter','latex')

but no big difference there. C and m are displayed as text and not their Value.

[Cris LaPierre]

Vaules displayed in purple are text and not variables. You need to do something like what you were doing before if you want to use the values of C and m and not the letters C and m.

I might write my callback functions for each edit field like this.

% Value changed function: mEditField
function mEditFieldValueChanged(app, event)
    C = app.CEditField.Value;
    m = app.mEditField.Value;
    title(app.UIAxes,"Plot of $"+ C + "*\sin(" + m + "*x)$",'Interpreter','latex')
end

% Value changed function: CEditField
function CEditFieldValueChanged(app, event)
    C = app.CEditField.Value;
    m = app.mEditField.Value;
    title(app.UIAxes,"Plot of $"+ C + "*\sin(" + m + "*x)$",'Interpreter','latex')
end
