Plotting Sparse Matrices

A convenient way to plot sparse matrices is with the function MatrixPlot. It is defined in the package LinearAlgebra`MatrixManipulation` and described in greater detail in the section Plotting Matrices. Note that in order to use the function, the package must first be loaded.

In[1]:=

This reads in a sparse matrix, using the Import function demonstrated in the previous section.

In[2]:=

Out[2]=

The matrix can be plotted. This is a useful way to see the structure of the matrix.

In[3]:=

If the matrix is multiplied with itself the result is less sparse, but it still has a related structure.

In[4]:=
