How can I enter this equation in matlab?

How do I enter this function into a script file? V is a function of R, and k1, CA0, X, Fa,in and k2 are defined, I just don't know how to tell matlab to evaluate that function with the upper and lower bounds as specified by the brackets. Thanks!

Use a function handle.

f = @(X) (R+1)*F*(-log(1-X)/k1/C + k2*C*X/k1 - k2*C*X^2/2/k1);
V = feval(f, X0) - feval(f, R*X0/(R+1))
