I have a connectivity matrix
and I want a figure like this for my matrix.
How can I draw this using matlab? Please help.
A= [-1 -1 0 0 0 0 0 1 0 1 0 0 -1 1 1 -1 1 0 -1 1 -1 1 0;

Use the Graph and Network Algorithms functionality included in MATLAB once you've corrected your adjacency matrix.

Error using graph
Adjacency matrix must be square.
Should your adjacency matrix be 21-by-21 or 23-by-23?
