I tried using bold font for the Greek letters in my axis labels in Matlab but they don't seem to work.
For example:
xlabel('\mathbf{\rho}','Interpreter','latex')
I've tried other commands such as \bf but still it doesn't work.
Does anyone know how to get around this?
Thanks!
Use equation notation (as you would need in LaTeX) $$ and \boldmath
xlabel('\boldmath$\rho$','Interpreter','latex')
\boldmath will make bold everything in the next equation after it, so if you want only only partly bold, then separate the equation
xlabel('\boldmath$\rho$ $_i$','Interpreter','latex')
If you want multiple things bold, the same. Separate the equation and add a \boldmath before each bold section.
You can use mbox to have everything in one single equation. Source
xlabel('$\sqrt{\mbox{\boldmath $\rho$}_i}$', 'Interpreter','latex')
