Hello,
I have two lines in one figure, one is called error, and the other is typed by latex form as well as the first element of array x, but I tried to use sprintf, but the results are wierd

x=[1.1, 2.1, 3.1]
legend( 'Error',sprintf('\bf[$\bf\frac{t v_p}{r_{well}}$] (\bf$\Pi_1$) = %f', x(1)), 'Location','best','Interpreter','latex' )

plot(rand(1,10)) ;
hold on
plot(rand(1,10)) ;
legend( 'Error','$[\frac{tv_p}{r_{well}}](\Pi_1=)$','Interpreter','latex', 'Location','best')
set(gca,'FontSize',24)

I think this should work:
legend({'$\left[\frac{t v_{p}}{r_{well}}\right] \left(\Pi_{1}\right)$'}, 'Interpreter', 'latex', 'location', 'best')
