# Sparse Adjacency Matrix in MATLAB®

How to make Sparse Adjacency Matrixes in MATLAB® with Plotly.

## Plot Sparsity Pattern

Plot the 60-by-60 sparse adjacency matrix of the connectivity graph of the Buckminster Fuller geodesic dome. This matrix also represents the carbon-60 molecule and a soccer ball.

B = bucky;
spy(B)

# Specify Color and Marker

B = bucky;
spy(B,'green')

# Specify Marker Size

B = bucky;
spy(B,'red',2)
