How to plot a 2D graph using for loop values?
显示 更早的评论
Hello, Could anyone tell me what the problem is in the following code?
Many thanks.
% code:
lambda= [1.5:0.005:1.6];
llambda=length(lambda);
for di=1:llambda
k(di)=2*3.14/lambda(di)
end
lambda= [1.5:0.005:1.6];
plot(lambda,k);

Whats wrong with it and why is the plot not what you're looking for? the code matches what the plot should be.
also no need for the for loop as
if true
lambda= [1.5:0.005:1.6];
k=2*3.14./lambda;
plot(lambda,k);
end
accomplishes the same thing

I am trying. The main question is why is the plot in your sample code not what you're trying to get. If it is then what is the question or is the question to plot within the for loop?

The code works fine:
lambda= [1.5:0.005:1.6];
llambda = length(lambda);
for di = 1 : llambda
k(di) = 2 * 3.14 / lambda(di)
end
plot(lambda,k);
It plots with absolutely no warnings or errors about different lengths. What is the actual code you ran (it's not that , that's for sure)?
