Hi, so I have this label which works fine. However, I've created a function in which the exponent varies (1/4). Therefore, I put a variable m in there and used num2str but the label doesn't come up right....
How could I apply num2str in the exponent for this case?
xlabel('$\it{\bf{(f_{ohm}P)^{1/4}}}$','Interpreter','Latex','FontSize', 15 )

share the code part of using num2str. What kind of result you are expecting?

This is what comes out...

m5 = 1/4;
xlabel(['$\it{\bf{(f_{ohm}P)^{num2str(m5)}}}$','Interpreter','Latex','FontSize', 15 ])
ylabel('$\it{\bf{\Lambda^{1/2}}}$','Interpreter','Latex','FontSize', 15 )
This is what I want

You can use rats function to get what you need actually.
Try this below:
m = 1/4;
a = ['$\it{\bf{(f_{ohm}P)^{',rats(m), '}}}$'];
xlabel(a,'Interpreter','Latex','FontSize', 15 );

Luna, what should I do if ‘m’ is a decimal?

If you define m = 0.25, you will see rats function still works as 1/4.
