# GraphSpread v0.1.0
## New Features
* Functions for working with the normalized Laplacian matrix
- `nlapl_matrix(G)` returns the normalized Laplacian matrix of ``G``
- `nlapl_spectrum(G[, k=2; which=:normalized]` returns the spectrum of the
normalized Laplacian
* Functions for computing isoperimetric parameters
- `conductance(G, X)` returns the conductance of ``X`` as a subset of ``V(G)``
- `edge_expansion(G, X)` returns the edge expansion of ``X`` as a subset of
``V(G)``
- `vert_expansion(G, X)` returns the vertex expansion of ``X`` as a subset of
``V(G)``
- `isoperimetric_num(G)` returns the isoperimetric number of ``G`` and a set
for which the conductance attains a minimum
- `cheeger_const(G)` returns the cheeger constant of ``G`` and a set for which
the edge expansion attains the minimum
