LaTeX interpreter is not working correctly with code including subscripts in Control System Toolbox legends
显示 更早的评论
When running the following code:
G1 = tf(1,[1,1,1]);
G2 = tf(1,[1,0.5,1]);
step(G1,G2);
h = legend('$G_1(s)$','$G_2(s)$');
h.Interpreter = "latex";
h.FontSize = 12;
We can observe that the subscripts are not displayed correctly in the legend. I would appreciate any solution for this bug. Thanks!

This is Not a Bug. In LaTeX, A_bc will only treat b as a subscript. In order to include multiple symbols in a subscript (or superscript) you need to group them with curly braces.
For instance, here is A_bc: 
while here is A_{bc}: 
.
while here is A_{bc}: .2 个评论

In fact, there is a way to solve this: plotting something into the figure before and overwriting the legend:
figure; hold on;
plot(0,0);
plot(0,0);
G1 = tf(1,[1,1,1]);
G2 = tf(1,[1,0.5,1]);
stepplot(G1,G2);
h = legend('$G_1(s)$','$G_2(s)$');
h.Interpreter = "latex";
h.FontSize = 12;
You can see that the subscripts are correctly displayed now.
