# 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
