用matlab做了个积分,算出的结果我看不懂,希望知情人士能帮小弟个帮>> int(int(int(l1,'p','0','pi'),'q','0','2*pi'),'c','0','t')ans =(-4)*pi*(log(-t)*(t - x2) - limit(c + log(c - t)*(t - x2),c = t,Left))

int(int(int(l1,'p','0','pi'),'q','0','2*pi'),'c','0','t')
int(l1,'p','0','pi'为第一重积分,l1是被积分的函数,p为自变量,0,pi,为积分的上下限
int(int(l1,'p','0','pi'),'q','0','2*pi')为第二重积分q为自变量,0,2*pi,为积分的上下限
int(int(int(l1,'p','0','pi'),'q','0','2*pi'),'c','0','t')为第三重积分c为自变量,0,t,为积分的上下限
