I have a problem with Matlab. Do you know a function that plots graphs? I have a matrix that gives me information about its links and I have to draw some of them to connect the vertices. I've tried using "gplot" but it doesn't work. Thank you so much!

1The basic function to plot graphs in Matlab is `plot(x,y)` but your question isn't precise enough to know what you want to plot exactly. If you need something more low level there's `line` as well. – meneldal Jul 08 '14 at 20:46

I have to draw 33 vertices and I have to link them using the information given in a matrix. Let's give an example: element in position 12 is different from zero, so I put a link between vertices 1 and 2; element in position 13 is zero, so I put no link. – user3818040 Jul 08 '14 at 21:16

@user3818040 what is your input? Why is gplot not working? – Daniel Jul 08 '14 at 21:35

My input is a matrix. Gplot doesn't give me the graph I want. – user3818040 Jul 08 '14 at 21:37

in this case you need to use the `line` function to draw each line separately because it doesn't seem to be something you can do with a regular plot function unless you change your data. A nice way is using NaNs to say you don't want this value to be plotted and make some "holes" in the continuous line you get from `plot` – meneldal Jul 08 '14 at 22:28

From your comments above, it sounds as if you are looking to plot a "Graph" in the sense of connections between nodes.
This post appears to contain several answers that are likely to be helpful to you.
If not, please give a concrete example of your input and we can probably help you.
