how to write superscripts in axis labels?

when I wrote the following plot. I couldn't get the superscript in labels.Can you guys help me. Thank you.

d = [ 2 4 5 7] d5l =1*[0.8839 2.45 13.59 5.492] plot(d,d5l,'--kd','markersize',20,'markerfacecolor','k') str1=' bell diameter $$d $$[cm]' str2='$$|\overline{Q}|$$ [cm^2/s]' legend('x/d = -1') xlabel(str1,'interpreter','latex','fontsize',30,'fontweight','bold') ylabel(str2,'interpreter','latex','fontsize',30,'fontweight','bold') set(gca, 'FontSize', 35,'fontweight','bold'); box on

%%can you look on yaxis label

d = [ 2 4 5 7]; d5l =1*[0.8839 2.45 13.59 5.492]; hold on plot(d,d5l,'--k^','markersize',20,'markerfacecolor','k'); str1=' bell diameter $$d $$[cm]'; str2='$$|\overline{Q}|$$ [cm^{2}/s]'; legend('x/d = -1'); xlabel(str1,'interpreter','latex','fontsize',30,'fontweight','bold'); ylabel(str2,'interpreter','latex','fontsize',30,'fontweight','bold');

set(gca, 'FontSize', 35,'fontweight','bold'); box on

To get a subscript you must use the underscore "_" character and for superscript use "^". For example:

 plot(1:10)
 title('^{super} normal _{sub}')

%%can you look on yaxis label
d = [ 2 4 5 7];
d5l =1*[0.8839 2.45 13.59 5.492];
hold on
plot(d,d5l,'--k^','markersize',20,'markerfacecolor','k');
str1=' bell diameter $$d $$[cm]';
str2='$$|\overline{Q}|$$ [cm^{2}/s]';
legend('x/d = -1');
xlabel(str1,'interpreter','latex','fontsize',30,'fontweight','bold');
ylabel(str2,'interpreter','latex','fontsize',30,'fontweight','bold');
set(gca, 'FontSize', 35,'fontweight','bold');
box on

str2='$$|\overline{Q}|$$ [cm^{2}/s]';
% should be 
str2='$$|\overline{Q}| [cm^{2}/s]$$';
