MATLAB爱好者论坛-LabFans.com - 【求助】请教高手如何实现几个matlab小程序的调用，谢谢

非常感谢你能打开这个帖子，我是matlab的初学者，以前在学校学过用过一下子matlab，现在基本上还给我的老师了，工作遇到了要用matlab，有些问题不懂，想让高手指点一下子，就是matlab中的小程序如何衔接调用，譬如附件中的几个matlab的程序，基本上能看懂，但是就是不知道怎么衔接起来，还有一些设定参数不知道怎么改变调整。清高手指点一下子，见笑了。谢谢。

1.稳态解程序

1.3运行chengxu.m后，得到10个方程，组成非线性常微分方程组，用i'数rigid.m表示:
%rigid.m
function dx=rigid(t,x)
dx=zeros(10,1)
dx(1)=800/9-20/9*x(1);
dx(2)=1280/9-20/9*x(2)-570/71*x (2)/(20+x(2))*x(5)+100*x(4);
dx(3)=800/9-1/10*x(3)+21/625*x(5)+7/1000*x(6);
dx(4)=3200/9-1001/10*x(4)+279/625*x(5)+93/1000*x(6);
dx(5)=640/3-29/50*x(5)+57/10*x(2)/(20+x(2))*x(5);
dx(6)=1/4 50-1/5 *x (6)+9/23* x( 9)/(1/2+x(9))*x( 6);
dx(7)=6637/10 00*x(7)-1653/710*x(2)/(20+x(2))*x(5)-1299/184*x(9)/(1/2 +x(9))*x(6);
dx(8)=-20/9*x(8)+75/46*x(9)/(1/2 +x(9))*x(6);
dx(9)=250/9-20/9*x(9)-2451/5 000*x(2)/(20+x(2))*x(5)+43/5000*x(6);
dx(10)=40/3-20/9*x(10)-2451170000*x(2)/(20+x(2))*x(5)-37887/161000*x(9)/(1/2+x(9))*x(6);

1.4 用龙格一库塔法解上面的常微分方程组，
%main.m
xO=[40 1.5 889 30 1450 90 150 40
[T,X]=ode45('rigid',[O 0.001],x0)
程序为main.m:
