Why MATLAB cannot render $\Beta$ (LaTeX string) in xlabel, ylabel?

Hello, everone!

By accident I find MATLAB cannot render $\Beta$ (LaTeX string) in xlabel, ylabel? I have set the "interpreter" to "latex". Is this means that MATALB does not support the whole Greek alphabet? I am using MATLAB R2021b (trial version). This is the sample code.

>> xlabel('$\beta$', 'interpreter', 'latex'); ylabel('$\Beta$', 'interpreter', 'latex')

Warning: Error updating Text.

String scalar or character vector must have valid interpreter

syntax:

$\Beta$

Besides, "$\Gamma$" works.

Thank you!

For an upper case beta, just use B and not \Beta.

Here's the characters you can use: https://www.mathworks.com/help/matlab/creating_plots/greek-letters-and-special-characters-in-graph-text.html

You'll note that characters like an upper case Beta and Epsilon aren't included because you can just use B and E and not \Beta and \Epsilon.

MATLAB's latex does not specifically support Greek. Instead, it supports some mathematical symbols, some of which happen to resemble Greek letters. You can see the chart at https://www.mathworks.com/matlabcentral/answers/14751-greek-alphabet-and-latex-commands-not-a-question?s_tid=srchtitle

Generally speaking, it does not bother to have \ codes for letters that are representable in English.

A B \Gamma \Delta E Z H \Theta I K \Lambda M N \Xi O \Pi P \Sigma T \Upsilon \Phi X \Psi \Omega
