drawing graph (0 and 1)

I have one matrix and i drew a bipartite graph Like below in MATLAB .

F =

     1     0
     2     1
     3     0
     4     0
     5     1
     6     0

plot(F','-*','Color','b','LineWidth',1,'MarkerEdgeColor','r')

axis([0, 3, -2, size(F, 1) + 1])

In this case all line are connected (0 and 1) of 2nd column separately. But I want to connect only if the element of 2nd column is equal to 1. No need for 0. How can I draw or how can I write code in MATLAB?

Solution

  • Just change:

    plot(F','-*','Color','b','LineWidth',1,'MarkerEdgeColor','r')

    ... to:

    plot(F(F(:,2) == 1,:)','-*','Color','b','LineWidth',1,'MarkerEdgeColor','r')

    By changing F to F(F(:,2) == 1,:) you're telling Matlab to use only the rows of F where the second column equals to 1.
