Mixed LaTeX math and text in Matlab

How can I mix LaTeX text and math modes?

At the moment I have things like : '$\theta_{Co}$'. In a plot, It works and the subscript Co comes out in math style italics. Sweet.

I now want the subscript to print out as normal text.

In Overleaf - LaTeX IDE that I'm using - I can write \theta_{\text{Co}}$ and that comes out as i want - When I try that in Matlab it prints out the string as the code \theta_{\text{Co}} . What can I do?

Thanks, David

Hi David,

It seems you're trying to mix LaTeX text and math modes in MATLAB but aren't getting the desired output. To fix this, you can use the “\mathrm” command within the math mode.

This command renders text in an upright (roman) font within a math expression, ensuring that non-mathematical symbols are styled correctly.

Here is a sample code, which prints “$\theta_{Co}$” same as your desired output ():

figure;  

% Plotting random data  
plot(1:10, rand(1, 10));  
title('$\theta$', 'Interpreter', 'latex');  
xlabel('x');  
ylabel('y');  

% Add a text annotation with LaTeX formatting  
text(5, 0.5, '$\theta_{\mathrm{Co}}$', 'Interpreter', 'latex');
