q = quadl(fun,​a,b,tol,tr​ace,p1,p2,​...)

Hi Dear Matlab Users;

I want to use quadl function using my function and then integrate it numerically.

Matlab function reference says

quadl(fun,a,b,tol,trace,p1,p2,...) provides for additional arguments p1,p2,... to be passed directly to function fun, fun(x,p1,p2,...)

I tried it just below but it gives me error. What is the problem ? I could not understand.

syms s zeta z1

k=quadl('ahmet',-1,1,[],[],s,zeta,z1)

function out = ahmet(r,s,zeta,z1)

syms z1 s zeta

out=2*r.^2*s.^4*zeta*z1;

end

It gives an error just below

Undefined function 'isfinite' for input arguments of type 'sym'

I want to integrate numerically my function for r variable -1 to 1. The other input arguments want to remain like constant because after integration of r; then I will integrate for s; for zeta; for z1 too by numerically.

I tried my function integration using int() command but it can not be evaluated analytically. I have to use numeric integration. I gave an example just. My function is more complicated to integrate.
