how to change latex default font in figure？

set(STA1,'A_Label','String','$(i+n)-C_{10}$','Interpreter','latex','FontSize',18,'FontWeight','bold')

When I use latex interpreter ，it can‘t use Times new roman style。how to solve this problem？

（在使用Latex编译器画图时，发现只能使用默认字体，不能更改为新罗马字体，如何解决？）

As far as I know, you can not set/change fonts for any text with Latex as the Text interpreter in MATLAB.

That functionality is not supported in MATLAB yet.

Install and Configure LaTeX:

• Ensure that you have LaTeX installed on your system, as MATLAB relies on LaTeX for rendering text with the LaTeX interpreter.

Specify the Font in LaTeX:

• Inside your LaTeX expression in MATLAB, you can specify the font you want to use by adding a LaTeX command like \usepackage{newtxtext}. For Times New Roman, you can use the newtxtext package.
• Here's an example of how to use Times New Roman in your LaTeX expression:

set(STA1, 'A_Label', 'String', '$\usepackage{newtxtext}$(i+n)-C_{10}$', 'Interpreter', 'latex', 'FontSize', 18, 'FontWeight', 'bold')

Make Sure LaTeX Can Find the Font:

• Ensure that LaTeX can find the font package you specified. If you've installed LaTeX packages recently, it might require updating LaTeX's font database. You can typically do this by running texhash or mktexlsr in your LaTeX distribution.

Recompile the Plot:

• After making the changes, recompile your plot, and it should now use the Times New Roman font for the specified text.

Thanks，I had solved this problem by you enlighten!

but,I modified code,used latex code,

set(STA1,'A_Label','String','$\mathrm{\mathbf{A_{10-14}TEST_{(i+j)}}}$','Interpreter','latex','FontSize',14)

[Hassaan]

You are welcome.

Hi there, the font is still times new roman in your modified code

set(STA1,'A_Label','String','$\mathrm{\mathbf{A_{10-14}TEST_{(i+j)}}}$','Interpreter','latex','FontSize',14)

Did you figure it out how to use some else font like Arial?

I am wondering whether this method is applicable in Matlab2018Rb?

I found it could not be translated:

"字符串标量或字符向量必须具备有效的解释器语法:

$\usepackage{newtxtext}$H_{z}$"

[Walter Roberson]

\usepackage is not a supported latex feature, except possibly for the report generator (and just maybe for certain operations related to uifigures)

xlabel('$\usepackage{newtxtext}$(i+n)-C_{10}$', 'Interpreter', 'latex', 'FontSize', 18, 'FontWeight', 'bold')

Warning: Error updating Text.

String scalar or character vector must have valid interpreter syntax:
$\usepackage{newtxtext}$(i+n)-C_{10}$
