While loop inside for loop fibonacci

So I want function to plot the fibonacci series and i want it to stop when it recheas m.

I'm not sure what the error is, it just doesn't run.

Thanks for helping!

function f = fibbo3(m)

n=100;

f=zeros(1,n);

f(1)=1;

f(2)=1;

for k=3:n

while f(k) <= m

f(k) = f(k-1) + f(k-2);

end

end

end

Don't have the while loop. After you assign f(k), just break if the value is more than m

for k=3:n 
        f(k) = f(k-1) + f(k-2);
        if f(k) >= m
            break;
        end
end

It works gret, only one problem with it. When I call my function with 12 for example, it looks like this:

1 1 2 3 5 8 13

I don't want the 13 to appear, any tip on how to make show everything up to and equal to "12"?

When you call it, print out the last one:

 f = fibbo3(m);
fprintf('The final Fibonacci number with m=%d is %d.\n', m, f(end));

Or else don't pass back the entire array, just pass back the last element:

function f = fibbo3(m)
% code.... then....
f = f(end); % Extract only the very last element of the vector to pass back.
