Hey Abdulrahman,

Based on what I can understand I think there is a logical error in the 15th line of your code. F_of_u is a function of x and not u_of_x. Therefore there is nothing the subs command can replace. Also if needed you can refer to the documentation for the subs() function.

You cannot integrate with respect to a function. You need to integrate with respect to a variable.

You might wish to do a change of variable, perhaps.

syms Lv
xv = solve(Lv=L,x);
Fv = subs(F,x,xv);
intv = int(Fv,Lv);
result = subs(intv, Lv, L);

MATLAB: Error using vertcat – Dimensions of matrices being concatenated are not consistent

You can use the debugger: Set a breakpoint in this line, run the code again, and when Matlab stops check the dimensions of the variables. The error message tells you, that they have a different number of columns.
