Question

Matlab 解复杂方程组如何解？

s=solve('x(e^(1/(y*26))-1)=1','x(e^(1.5/(y*26))-1)=80');s.x,s.y
??? Error using ==> mupadmex
Error in MuPAD command: cannot differentiate equation [numeric::fsolve]

Error in ==> sym.sym>sym.mupadmexnout at 2018
out = mupadmex(fcn,args{:});

Error in ==> solve at 76
[symvars,R] = mupadmexnout('symobj::solvefull',eqns,vars);
帮我看一下是什么错误，顺便帮我解一下这个方程组，谢谢了，在线等
我不会用matlab，所以只把方程组解了也可以，
'x(e^(1/(y*26))-1)=1',
'x(e^(1.5/(y*26))-1)=80'

Answer 1

s=solve('x*(exp(1/(y*26))-1)=1','x*(exp(1.5/(y*26))-1)=80');
s.x,s.y

结果：
s =

x: [1x1 sym]
y: [1x1 sym]

>> s.x

ans =

0.00015632267679000363133741067619345

>> s.y

ans =

0.0043887105806899711003210265856282
