Dear Helpers,
I'd like to plot some data and annotate the YAxis according to the following code using the latex interpreter:
plot(Tx',drhodT','LineWidth',1.5)
legend(LoF,'Location','eastoutside')
grid on
xlabel('Temperature [K]')
ylabel('$\frac{\partial\rho}{\partial T}$ [kg/m³/K]','Interpreter','latex')
When plot appears, also following error message is enclosed.

I wonder why the error message shows two backslashed instead of one single backslash which I coded.How to rectify this problem.
Looking forward to receiving your suggestions.
Best regards
Tom

ylabel('$\frac{\partial\rho}{\partial T} [kg/m^3/K]$','Interpreter','latex')
The ³ character is not accepted for latex
To correct for that you need to use ^ but that is only accepted inside $$
You should probably rewrite the unit using frac

Walter's answer works for me.
plot(1:20,rand(1,20),'LineWidth',1.5)
legend('data','Location','eastoutside')
grid on
xlabel('Temperature [K]')
ylabel('$\frac{\partial\rho}{\partial T} [kg/m^3/K]$','Interpreter','latex')
Which version of MATLAB are you using?

Let us experiment:
figure()
subplot(1,4,1)
ylabel('\frac{\partial\rho}{\partial T} kg/ m³', 'interpreter', 'latex'); title('A1');
subplot(1,4,2)
ylabel('$\frac{\partial\rho}{\partial T} kg/ m³$', 'interpreter', 'latex'); title('A2');
subplot(1,4,3);
ylabel('\frac{\partial\rho}{\partial T} kg/ $m³$', 'interpreter', 'latex'); title('A3');
subplot(1,4,4);
ylabel('$\frac{\partial\rho}{\partial T} kg/$ m³', 'interpreter', 'latex'); title('A4');
figure()
ylabel('m³', 'interpreter', 'latex'); title('AA1');
figure()
ylabel('$m³$', 'interpreter', 'latex'); title('AA2');
figure()
ylabel('m^3', 'interpreter', 'latex'); title('AA3')
figure()
subplot(1,4,1)
ylabel('\frac{\partial\rho}{\partial T} kg/ m^3', 'interpreter', 'latex'); title('B1');
subplot(1,4,2)
ylabel('$\frac{\partial\rho}{\partial T} kg/ m^3$', 'interpreter', 'latex'); title('B2');
subplot(1,4,3)
ylabel('\frac{\partial\rho}{\partial T} kg/ $m^3$', 'interpreter', 'latex'); title('B3');
subplot(1,4,4)
ylabel('$\frac{\partial\rho}{\partial T} kg/$ m^3', 'interpreter', 'latex'); title('B4');
figure();
subplot(1,4,1)
ylabel('\frac{\partial\rho}{\partial T} kg/ m³', 'interpreter', 'tex'); title('C1');
subplot(1,4,2)
ylabel('$\frac{\partial\rho}{\partial T} kg/ m³$', 'interpreter', 'tex'); title('C2');
subplot(1,4,3)
ylabel('\frac{\partial\rho}{\partial T} kg/ $m³$', 'interpreter', 'tex'); title('C3');
subplot(1,4,4)
ylabel('$\frac{\partial\rho}{\partial T} kg/$ m³', 'interpreter', 'tex'); title('C4');
figure();
subplot(1,4,1)
ylabel('\frac{\partial\rho}{\partial T} kg/ m^3', 'interpreter', 'tex'); title('D1');
subplot(1,4,2)
ylabel('$\frac{\partial\rho}{\partial T} kg/ m^3$', 'interpreter', 'tex'); title('D2');
subplot(1,4,3)
ylabel('\frac{\partial\rho}{\partial T} kg/ $m^3$', 'interpreter', 'tex'); title('D3');
subplot(1,4,4)
ylabel('$\frac{\partial\rho}{\partial T} kg/$ m^3', 'interpreter', 'tex'); title('D4');
You can see from AA1 and AA2 that you can include the ³ character in latex, and it will give you the ³ output, but that it will generate the warning message regardless of being inside $$ or not.
You can see that the only one of these that works as you would hope is B2: $\frac{\partial\rho}{\partial T} kg/ m^3$ intepreter latex.
You can see from the A series that when the ³ character is included, that the entire string goes uninterpreted and is just put up (some as if you used interpreter 'none')
You can also see that when you use ^ to get the raised 3, then that can work -- but only if you are inside $$

This worked for me.
ylabel('$Dichte\ddot{a}nderung \, \left.\frac{\partial\rho}{\partial T}\right|_{x=0} [kg/m^3/K]$','Interpreter','latex')
