[Matplotlib-users] Visualizing Sparsity Pattern of matrices

[Nils W. <nw...@me...>]

Hi all,

Structure plots provide a quick visual check on the sparsity pattern of 
the matrix.
A structure plot is a rectangular array of dots;
a dot is black if the corresponding matrix element is nonzero otherwise 
it is white.

Is it possible to generate such plots with scipy or should we switch 
over to matplotlib ?
