求解带有变限积分方程式。

syms x t
solve(1-0.1864+4/x*(1/x*(int(t/(exp(t)-1),0,x))-1))
错误使用 mupadengine/feval (line 157)
MuPAD error: Error: The second argument must be of form x or x = a..b. [int]
出错 solve (line 170)
sol = eng.feval('symobj::solvefull',eqns,vars);
请问这是什么问题啊?

积分没有解析式。
只能用数值方法。
fsolve(@(x)1-0.1864+4./x.*(1./x.*integral(@(t)t./(exp(t)-1),0,x)-1),1)
ans=1.7266
