Matlab出现此上下文中不允许函数定义

可能你的程序格式有问题。如把代码集成在一起，可以来写

function ode45_main( )

clear all%清除内存中的变量和和函数

tspan=[0,0.245]%定义变量的求解区间

y0=[0.449/0.09846,0.1021/0.09846,0.1057/0.09846,0.019/0.09846,0.2327/0.09846,0.085/0.09846,1.01325,1,1273]%定义初始值-v=0.669

[z,y]=ode45(@redu_model_fun,tspan,y0)

A=[z,y]

disp('    z,    y ')

disp(A)

end

function dy=redu_model_fun(z,y)

n=y(1)+y(2)+y(3)+y(4)+y(5)+y(6)

。。。。。。

dy(9)=1/(y(8)*SigmaNC)*(-SigmarH-y(8)*dy(7)-y(7)*dy(8)-SigmaRC*y(9))

end

然后，保存为 ode45_main.m 文件

运行可得

Yo one to the

Two to the three to the four

Maare vo entry tho

Majaaaye shor

Swagger galore

So hard kaur

Ee sarrainodu aaya

Hiljaaye floor

Ye rangu rangu cycle ekki

Tinguranga vacchinaade pillagaadu

Ye tring-u tring-u bell-u kotti

Mundu side-u yekkamantu pilichinaadu

Nuvvu manchi pillagaadu

Kaani nee lopadlo kandirodu

Eththupalla mosthe nannu

Sittu sittu cheyyakunda oorukodu

Soodhi guchchinode
