LaTex Font has changed since update

I want my font on my figues and tables to match the rest of what i am writing, so I ussually use the LaTex font in matlab when making figues.

In the start of the script I would write:

set(groot,'defaultAxesTickLabelInterpreter','latex')

set(groot,'defaulttextinterpreter','latex')

set(groot,'defaultLegendInterpreter','latex')

However, since I hav updated my MatLab to R2023b, the font has changed.

I have attached eksample of how it looked before and after the update.

Granted symbols like μ and sub- and superscrpts still work as it ussually did.

Hello Tias,

I assume that you are working in a MATLAB Live Script. To fully appreciate the updated font formats, including LaTeX-rendered text in MATLAB figures created within a Live Script, please follow these steps to view the changes in detail:

1. Execute your Live Script to generate the figure.
2. Find the Embedded Figure within the Live Script editor.
3. Click on Open in figure window at the right-top corner of the embedded figure to view it in a separate window for a clearer visualization of the font changes.

Here is an example code that demonstrates setting font sizes and using in figure labels:

% Set default interpreters to 'latex' for consistent font styling
set(groot, 'defaultAxesTickLabelInterpreter', 'latex');
set(groot, 'defaultTextInterpreter', 'latex');
set(groot, 'defaultLegendInterpreter', 'latex');

% Optionally, set a consistent font style, e.g., 'Times New Roman'
set(groot, 'defaultAxesFontName', 'Times New Roman');
set(groot, 'defaultTextFontName', 'Times New Roman');

% Generate sample data
x = linspace(0, 2*pi, 100);
y1 = sin(x);
y2 = cos(x);

% Plot the data with customized line widths
plot(x, y1, '-r', 'LineWidth', 2);
hold on;
plot(x, y2, '-b', 'LineWidth', 2);
hold off;

% Set labels and title with LaTeX formatting and customized font sizes
xlabel('$x$ (radians)', 'FontSize', 18);
ylabel('$y$', 'FontSize', 18);
title('Plot of $\sin(x)$ and $\cos(x)$', 'FontSize', 20);

% Add a legend with a customized font size
legend('$\sin(x)$', '$\cos(x)$', 'FontSize', 16);

After running this script in a MATLAB Live Script, open the figure in a separate window through the Open in figure window option for the best visualization of your -formatted labels and titles. This allows you to inspect the precision of the font rendering and adjustments made.

I hope this helps!

This does not help. Mathworks has changed the LaTeX fonts between 2024 and 2025 as shown in the two images. The first image is the identical .FIG file opened in 2024B and the second is the .FIG file opened in 2025B. The new fonts are worse and not consistent with standard LaTeX CMR and CMMI fonts. They are unattractive and have changed for no reason. Along with a variety of other changes made in 2025, why were they made? Equally important, how can I switch them back?
