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

113 views (last 30 days)
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}')

Hello Chen
Thanks for your reply.
Actually, I'd like to display R in blackboard bold type (see for instance, 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, which lets you overlay eps figues with LaTeX code.
Kind regards

Use ℝ (Unicode Decimal Code &#8477)
ylabel('\alpha \in ℝ')
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'
