I am getting this error msg. Please find me the mistakes here.
In an assignment A(I) = B, the number of elements in B and I must be the same.
r=[2.0 3.1 3.5 3.65 3.84 3.95];
x=[];
x(1)=0.35;
f=@(x) r*x*(1-x);
N=40;
for t=1:N-1;
x(t+1)=f(x(t));
end
hold on
plot(x,'r-')

yes thats because you are including information that is not here and in your other posting that was flagged. but looks like you have it so we're all set?

only rude comment from me would be that posting on a forum for assignment questions involving things besides what type of functions to use, function errors, random matlab issues, and approaches to handling data is cheating. The Teaching Assistant or office hours should be where assignment related questions be asked.

And it’s not cheating to have MATLAB Answers do your homework for you?

Were you attempting to do this?
r=[2.0 3.1 3.5 3.65 3.84 3.95];
x=[];
x(1,:)=0.35*ones(size(r));
f=@(x) r*x*(1-x);
N=40;
for t=1:N-1;
x(t+1,:)=f(x(t));
end
hold on
plot(x)
legend('r = 2.0','r = 3.1', 'r = 3.65')
Where the first value of x is 0.35? or you can re-write it such that the function
f=@(x,r) r*x*(1-x);
such that you write a for loop to cycle in the r you need.

no it doesn't make sense. how do they look different? shape? amplitude?
