how to write mark _ in plot label in matlab

To write a mark (subscript) in a plot label in MATLAB, you can use LaTeX syntax. For example, to write a label with a subscript, you can use the following code:

main.m
xlabel('$x_1$');
ylabel('$y_{max}$');
38 chars
3 lines

In this code:

• The $ symbol is used to enclose the LaTeX expression.
• The _ symbol is used to create a subscript.

You can also use other LaTeX syntax, such as:

• ^ to create a superscript: $x^2$
• \ to create a special character, such as \theta or \pi
• \text to create a text label with LaTeX syntax: $\text{Hello World}$

Note: Make sure to include the '$' symbols around your LaTeX expression to enable LaTeX rendering in MATLAB.
