[求助] 请问matlab解方程组结果如何保存 已有1人参与

matlab程序如下，想把运行结果保存至一.txt文件，便于用ORIGIN画图分析，请问该如何设置如下运算结果保存，期待大侠指导
function solve_noneqs2
clear all;clc
format long
global thita
x0=[0.8 -5 0.1];
for i=1:1:88
    thita=i*3.14/180.0;
[x]=fsolve(@objfun,x0)
end
function f=objfun(x)
global thita
gam=0.2;
gama=gam/(cos(thita)+gam*(1-cos(thita)));  
nn=0;

mie=1836.0*4.0;
miu=1.0/mie;
tie=0.01;
rou=0.2;
uiy0=-0.01;
e0=-0.01;
f(1)=(1+x(1))*x(3)-(1-gama)*sqrt(2*mie*pi)*exp(x(2))/(1+erf(sqrt(-x(2))));
f(2)=gama*x(3)/(1-gama)-x(1)*sqrt(nn*nn-2*mie*x(2))/(1+x(1));
f(3)=(1+erf(sqrt(-x(2)))+2*exp(x(2)))/(1+erf(sqrt(-x(2))))...
+(-x(1)/(miu*nn*nn-2*x(2)))-(1-rou*uiy0*sin(thita)/e0)/(x(3)*x(3)-tie);

或者更简单点，把x结果显示在主程序窗口中，复制粘贴到Origin即可：

function solve_noneqs2

    thita=i*3.14/180.0;
x(i,1:3)=fsolve(@objf ...

非常感谢您的每一次指导！祝每天开心

仅供参考，运行完毕后，请到D盘找名为 shuju.xls  的excel文档
CODE:

x0=[0.8 -5 0.1];
for i=1:1:88
    thita=i*3.14/180.0;
x(1:3,i)=fsolve(@objfun,x0);

end
xlswrite('D:\shuju.xls',x)


function f=objfun(x)
global thita
gam=0.2;
gama=gam/(cos(thita)+gam*(1-cos(thita)));  
nn=0;

mie=1836.0*4.0;
miu=1.0/mie;
