<｜begin▁of▁sentence｜>### Instruction:
Having an igraph object representing a full graph with 3 nodes, how can you visually represent its adjacency matrix using the MatplotlibMatrixDrawer.draw method?
### Response:
from igraph import Graph, Matrix
from igraph.drawing import MatplotlibMatrixDrawer
import matplotlib.pyplot as plt

# Create a graph
g = Graph.Full(3)

# Get the adjacency matrix of the graph
matrix = g.get_adjacency()
# Convert to igraph Matrix for MatplotlibMatrixDrawer
matrix = Matrix(matrix.data)

# Create a matplotlib figure and axis
fig, ax = plt.subplots()

# Create a MatplotlibMatrixDrawer instance
drawer = MatplotlibMatrixDrawer(ax)

# Draw the matrix
drawer.draw(matrix, cmap='viridis')
plt.show()
