[英]Please Explain Octave-Error : operator /: nonconformant arguments (op1 is 1x1, op2 is 1x10)
I have an issue running a certain script in octave. 我在以八度运行特定脚本时遇到问题。 This is the code that produces the error:
这是产生错误的代码:
#germanium
T=410:20:600;
x=linspace(400,410,100);
y=linspace(10^9,10^9,100);
k=8.5*10 .^(-5);
Eg=0.59;
Nc300=1.02*10^13;
Nc=Nc300*((T/300).^(3/2));
n=Nc*(e.^(-Eg/(2*k*T)));
plot(T,n,x,y,'m');
grid on
xlabel('Temprature');
ylabel('Electron Density n');
title('Germanium n(T)');
As mentioned in the Title, the error that is produced is the following: error: ger5: operator /: nonconformant arguments (op1 is 1x1, op2 is 1x10) I have done a lot of testing, and I figured that the problem originates from the T variable on the 9th line : n=Nc*(e.^(-Eg/(2*k*T))); 如标题中所述,产生的错误如下: 错误:ger5:运算符/:参数不一致(op1为1x1,op2为1x10)我做了很多测试,并且我认为问题出在第9行的T变量: n = Nc *(e。^(-Eg /(2 * k * T))); The codes run fine without it.
没有它,代码运行良好。 For example :
例如 :
#germanium
T=410:20:600;
x=linspace(400,410,100);
y=linspace(10^9,10^9,100);
k=8.5*10 .^(-5);
Eg=0.59;
Nc300=1.02*10^13;
Nc=Nc300*((T/300).^(3/2));
n=Nc*(e.^(-Eg/(2*k*500)));
plot(T,n,x,y,'m');
grid on
xlabel('Temprature');
ylabel('Electron Density n');
title('Germanium n(T)');
In which case I simply replaced T with 500 , the code runs perfectly fine. 在这种情况下,我只需将T替换为500,代码就可以正常运行。 Sadly T, can not be replaced by a certain number since it is the variable used in my graph.
遗憾的是,T不能用某个数字代替,因为它是我的图形中使用的变量。 Although I did some digging, I never managed to fully understand this error, or how to fix it, thus any help would be greatly appreciated.
尽管进行了一些挖掘工作,但我从未设法完全理解此错误或如何解决此错误,因此,我们将不胜感激任何帮助。 Thanks.
谢谢。
Add a . 添加一个。 before your *, /, and ^ signs.
*,/和^符号之前。 This will ensure that octave uses scalar multiplication instead of matrix multiplication.
这将确保八度使用标量乘法而不是矩阵乘法。
n=Nc.*(e.^(-Eg./(2.*k.*T)));
