（将MATLAB脚本转换为Octave脚本）输出图中的LaTeX渲染

Question

I am in the process of converting a Matlab script to an Octave one. I have pretty much completed the task - however, I am having problems using a particular LaTeX command to print out correctly.

I changed the line in the m script from:

ylabel('Foobar $F=\frac{A}{B}$','Fontsize',20,'FontWeight','Bold','interpreter','latex');

To

ylabel('Foobar $F=\frac{A}{B}$','Fontsize',20,'FontWeight','Bold','interpreter','tex');

However, this does not render correctly (the original character display on the plot - complete with the format specifiers).

I don't understand why this is the case, since I am successfully using LaTeX commands in the same plot - and those work correctly.

Is there something wrong with the LaTeX commands above?. It is supposed to render as a fraction (A over B).

Answer 1

The first command renders fine for me (using Matlab). The second does not.

Generally 'tex' expresses lower level concepts than 'latex' . This demonstrates that the frac construct is not available in the 'tex' interpreter.
