Writing legends for MATLAB figures with subscripts

What is the solution for writing legends for MATLAB figures with subscripts?

Hi Milad,

You can create legends with subscripts by using the LaTeX interpreter. Use the underscore character _ to denote subscripts, and set the interpreter to 'latex'.

Attaching a small code for reference:

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

plot(x, y1, x, y2);

% Create a legend with subscripts
legend({'$y_1 = \sin(x)$', '$y_2 = \cos(x)$'}, 'Interpreter', 'latex');

You can also refer to the documentation Add legend to axes - MATLAB legend (mathworks.com) for further reference.

@Milad: FYI, Interpreters 'tex' and 'latex' both support subscripts using the underscore character.

'tex' is the default interpreter.

plot(1:10)
legend('a_1')

thanks. good solution.

"How to use a special character like µ?"

Exactly as the documenation states, use LaTex markup:
