How can I insert a square root in y-axis of curve ?

Hi

Please see the program and rectify the sqrt .

Thanks

FVF = [0.86;0.89; 0.92 ; 0.95]*100;
teta_r = [3.17; 3.29; 3.41; 3.53]; 

figure (8)
plot(FVF,teta_r,'gx-','Linewidth', 2)
xlabel ( 'FVF (%)')
ylabel ('\theta (10^-3 C/m sqrt(kg))')

Good question, I don't know is the sqrt symbol is native (maybe by importing some latex ones), but you can use brackets {} and exponents form only

ylabel ('\theta (10^{-3} C.m^{-1}.kg^{1/2})')

Not sure if your kg unit is above or below the units fraction, add a - to adjust

Use: \surd (x) , incase you want to write √x on y-axis

For e.g.

ylabel ('Fracture Toughness (MPa\surd(m))')

You can use latex

ylabel('$$\theta \quad \left(10^{-3} \mathrm{C/m} \sqrt{\mathrm{kg}}\right)$$','Interpreter','latex')
