Help on this case. I am integrating a certain function with known upper and lower limits as per below but when I run it, the command window still shows an integral function and not a numerical value. Thanks and hoping for some help.
syms y
V = (2/3).*pi.*3.4.^3 .*(1-exp((-4.*100./300)*((1./y.^4)-(1./y.^2))));
B = int(V, y, 0, 10000);

If you want a numeric result, use vpaintegral (introduced in R2016b) instead of int. Not all expressions have analytic integrals.

V = (2/3).*pi.*3.4.^3 .*(1-exp((-4.*100./300)*((1./y.^4)-(1./y.^2))));
B = vpaintegral(V, y, 0, 10000)
