[求助] 用Matlab化简一个复杂含参积分式的函数表达式已有1人参与

急需化简一个复杂含参积分的表达式，表达式如上传图片所示：
用Matlab化简一个复杂含参积分式的函数表达式

由于积分式比较复杂，之前用matlab做了数值解，并验证正确了
format long
clc,clear
M=0.230873094;
N=0.025914445;
n=0.86;
exp=114.8;
wf0=46;
tH=300;
F = @(t,p1,p2,p3,p4,p5)(((p1./(1+t)-p2.*log10(1+t)./(1+t)).^p3./p4)-(p1./(1+t)-p2.*log10(1+t)./(1+t))./p5);
dc=quadl(@(x)F(x,M,N,n,exp,wf0),0,tH)

由于数值解分别计算一个一个案例非常麻烦，所以想要寻求一下图片所示公式的化简公式，并可以用于Excel等软件中批量处理。

“数值解分别计算一个一个案例”，对于不同的案例，积分式什么参数会改变？

M N exp n wf0 tH会变。所以想找一个含参的近似方程，怎样用MATLAB实现呢~

M N exp n wf0 tH会变，写个循环语句就解决了。
原积分式即便近似为一个代数式，M N exp n wf0 tH会变的情况下，一样麻烦。

如果我只有积分上限变化（tH），其余都不变，能基于上面的程序帮忙给一个程序吗，最好可以出图？

syms p1 p2 p3 p4 p5 tH t
F = (((p1./(1+t)-p2.*log10(1+t)./(1+t)).^p3./p4)-(p1./(1+t)-p2.*log10(1+t)./(1+t))./p5);
ff=int(F,t,0,tH);
latex(ff)

结果(不咋的)：
ans =

\int _{0}^{{\it tH}}\! \left( {\frac {{\it p1}}{1+t}}-{\frac {{\it p2}\,\ln  \left( 1+t \right) }{\ln  \left( 10 \right)  \left( 1+t \right) }} \right) ^{{\it p3}}{{\it p4}}^{-1}- \left( {\frac {{\it p1}}{1+t}}-{\frac {{\it p2}\,\ln  \left( 1+t \right) }{\ln  \left( 10 \right)  \left( 1+t \right) }} \right) {{\it p5}}^{-1}{dt}

以下代码是积分上限tH从100开始以间隔1变化到600的例子，可自行根据实际修改。
需注意以下代码为m文件格式，请新建一个m文件，把以下代码完整复制进去，再运行。
CODE:
function qiu_jifen
clear all;clc
format long
tH_0=100;    %积分上限tH的最小值
tH_n=500;    %积分上限tH的最大值
num=tH_n-tH_0+1;     %积分上限tH总的变化数目

tH_data=linspace(tH_0,tH_n,num);
for i=1:length(tH_data)
    tH=tH_data(i);
    dc(i)=quadgk(@obj,0,tH);
end
[tH_data' dc']
figure(1)
plot(tH_data,dc,'b-')

function f=obj(t)
M=0.230873094;
N=0.025914445;
n=0.86;
exp=114.8;
wf0=46;
p1=M;
p2=N;
p3=n;
p4=exp;
p5=wf0;
f=(((p1./(1+t)-p2.*log10(1+t)./(1+t)).^p3./p4)-(p1./(1+t)-p2.*log10(1+t)./(1+t))./p5);

计算结果：
