编写一个MATLAB函数给出的电流和所有必要的参数为输入

Question

h = 11;     
D = 0.02614;          
Tinfinity =302 ;   
sigma = 5.67*(10^-8); %Variables 
epsilon = 0.3;   
alpha = 0.6;   
Gs = 1200;    
R = 0.00007;  


for I=1:1:720 
pF1=@(T) h.*pi*D.*(T-Tinfinity)+sigma.*epsilon.*pi*D.*((T.^4)-  (Tinfinity.^4))-alpha.*D.*Gs-(I.^2)*R; 
T(I) = fzero(pF1,0); %T is temperature and I is current 

end 
plot (I,T)  %I cannot get it to plot a graph 
xlabel('Current ');    
ylabel('Temperature '); 

％我的问题是，我不能让它图表给出的所有变量，除了对于T什么，温度

Answer 1

时计算导线温度

我对你的代码做了一些改变，涉及到我的矢量和循环。请尝试以下代码：

h = 11;     
D = 0.02614;          
Tinfinity =302 ;   
sigma = 5.67*(10^-8); %Variables 
epsilon = 0.3;   
alpha = 0.6;   
Gs = 1200;    
R = 0.00007;  

II = [1: 1: 720] ; 
for I=1:length (II) 
pF1=@(T) h.*pi*D.*(T-Tinfinity)+sigma.*epsilon.*pi*D.*((T.^4)-(Tinfinity.^4))-alpha.*D.*Gs-(I.^2)*R; 
T(I) = fzero(pF1,0); %T is temperature and I is current 

end 
plot (II,T)  %I cannot get it to plot a graph 
xlabel('Current ');    
ylabel('Temperature '); 

在你的代码，我循环变量，它拿着循环的最终值是720。但是，你想要绘制的T Vs的我那么T的所有值密谋为一个单一的值。
