请教符号积分时遇到的问题
 

想解一个二重积分，看网上有人说可以先做符号积分int，再做数值积分quadv。可是我int那里就出问题了，不知道怎么解决。

clear;
syms t w
L=0.08;
a=0.1;b=0.08;c=-0.15;uz=0.2;vz=0.2;wz=0.1;
f1=[(-3/20+w)/((2/25-t)*(2/25-conj(t))+(-3/20+w)*(-3/20+conj(w)))^(3/2)+(3/20-w)/(1/25+(2/25-t)*(2/25-conj(t))+(-3/20+w)*(-3/20+conj(w)))^(3/2)+(-3/20-w)/((2/25-t)*(2/25-conj(t))+(-3/20-w)*(-3/20-conj(w)))^(3/2)+(3/20+w)/(1/25+(2/25-t)*(2/25-conj(t))+(-3/20-w)*(-3/20-conj(w)))^(3/2),
0,
1/5/(1/25+(2/25-t)*(2/25-conj(t))+(-3/20+w)*(-3/20+conj(w)))^(3/2)+1/5/(1/25+(2/25-t)*(2/25-conj(t))+(-3/20-w)*(-3/20-conj(w)))^(3/2)];
f2=int(f1,t,-0.1,0.1); %%%%%出错的地方
f2=inline(f2/L);
result=quadv(f2,w,-wz,-wz-L);

f1有点复杂，是个行向量，带有两个变量t和w；int是想对t求积分，quadv想对w求积分。

错误信息如上，不知道怎么解决。请各位大虾帮帮忙，谢谢！
