I have searched quite a bit for examples of displaying titles in latex. My goal is to show the following:

`Bin 0° <= \varphi_2 <= 5°`

Where \varphi is the variation of phi that normal TeX does not offer. I do not mind if the less than or equal to stays like that or becomes the fancy LaTeX form.

The example I found so far that does not give me any warning is from: https://www.mathworks.com/matlabcentral/answers/42448-about-latex-command-in-the-title, where the example is:

`title('$$Q \geq \frac{I_h H}{I_h H+I_z C}, b_1 \geq b_2$$','interpreter','latex')`

And it works as expected when I tried it.

I tried many things and eventually the following worked:

`title('Bin $$0^{\circ} \leq \varphi_2 \leq 5^{\circ}$$','interpreter','latex')`

Result:

`Bin 0° <= \varphi_2 <= 5°`
