Plot multiple curves on a graph (involving a for loop within another)

I have the code below:

I want to plot a jvals x vetor_momentoj curve. In this example, I would have 4 curves (it=4), each one varying according to the 3 points defined (n=3).

Can anybody help me, please?

P.S. this is just a test code, and the value 0.03 used to define jvals is hypotetical. In the real code this value depends on the index i. Also, the value that the variable vetor_momentoj is assuming is hypotetical as well.

Hi,

Here is a solution.

...
for ii=1:it
    jvals(ii,:)=linspace(0,0.3,n);
    for jj=1:n
        curvature=jvals(ii,jj);
        x0j=1;
        vector(ii,jj)=jj;
        plot(jvals(ii,:), vector(ii,:), '-o'), hold all
    end
end
...
    

Note that the values of jvals and vector can be generated easily without using for .. end loop. For larger sets of data, the loops are very inefficient.

it=4; n=3;
jvals=repmat(linspace(0,0.3,n),it,1)
vectors=repmat(1:n, it, 1);

Good luck.

Thank you! But the plot had to be outside the for inner loop ;) now it worked
