求助 如何对复杂的二元符号函数中的一个变量积分
 

function [intcf1,intcf2]=intcf

v = 0.4*340;
b = 0.09;
omg = 10*pi;

syms xx;
syms t;
intcf1=0;
intcf2=0;



cf1 =exp(omg*(t-xx/v))*(sqrt((xx+b)/(xx-b))-1);

cf2 =exp(omg*(t-xx/v))*(xx-sqrt(xx^2-b^2));
%要对以上两个表达式中xx项进行积分一下是我采用的方式
%直接用int得不到结果，所以我用离散后累加求和的方式
for c=b+0.0001:0.001:20

temp1= subs(cf1,'xx',c);

intcf1=intcf1+temp1*0.001;

end;

for c=b+0.0001:0.001:20

temp2= subs(cf2,'xx',c);

intcf2=intcf2+temp2*0.001;

end;

结果成了这个样子

希望大家能给与指教，能不能用其他的方法得到积分的结果？
