LaTeX Interpreter and Blackboard bold (\mathbb{}) for text

Hello

I'm creating a MATLAB plot to be exported in a LaTeX document in eps format.

For instance, I have the following ylabel command that works properly:

ylabel('$\alpha \in R$','Interpreter','latex')

However, if I try to use black board style in the text for the letter R this will not work:

ylabel('$\alpha \in \mathbb{R}$','Interpreter','latex')

I understand that the mathbb requires the amsmath package but I'm wondering if there is any other way to have that letter R in black board sytle.

Thanks in advance.

If that is all you want to do, you can use the default tex interpreter.

ylabel('\alpha in \bf{R}')

Use ℝ (Unicode Decimal Code &#8477)

ylabel('\alpha \in ℝ')

or

ylabel(sprintf("\\alpha \\in %c", 8477))

Note: you can only use unicode characters in R2015b or later, and you have to be using interpreter 'none' or interpreter 'tex' . It does not work with interpreter 'latex'

Hello Chen

Thanks for your reply.

Actually, I'd like to display R in blackboard bold type (see for instance http://en.wikipedia.org/wiki/Blackboard_bold), which is normally used for sets.

Thanks for any hint.

Hi Leo,

I've never done that so I don't know if it can be done. I could be wrong but my guess is no as it is not part of basic TeX or LaTeX and MATLAB only supports only a basic subset of TeX or LaTeX.

I would suggest you to contact technical support and get an authoritative answer on this.

Hi Chen,

There is a turnaround to get \mathbb{} in a MATLAB figure by using the psfrag package http://en.wikipedia.org/wiki/PSfrag, which lets you overlay eps figues with LaTeX code.

Kind regards

Hi Leo,

Good to know this trick, thanks for sharing.

Or just add asmath package to matlab-latex: http://stackoverflow.com/questions/12250919/how-do-you-use-the-latex-blackboard-font-in-matlab
