wgPlot - Weighted Graph Plot (a better version of gplot)

Plot graphs with weighted vertices and weighted edges from a weighted adjacency matrix.

Description

Plot graphs just like gplot. But allow user to input an adjacency matrix with weighted edges and/or weighted vertices. The Edge weights are mapped to a colormap. The vertex weights are proportional to the vertex size. Using parameter-value pairs, user can even specify the vertex scaling factor, edge width, and the colormap used to show other meta data associated with the vertices. (Couple of the graph included as example were from David Gleich's matlabBGL package.)

Even for a very simple example, i get an error:

>> wgplot(sprand(10,10,0.2), rand(10,2));

> In wgPlot at 36
  In corrcoeff at 44
??? Error using ==> ishghandle
Too many input arguments.

Error in ==> axesArea at 25
if ishghandle(varargin{1},'axes')

Error in ==> wgPlot at 36
axesArea(h,[6 7 5 5]);

What's wrong?

Very useful, nice display, computationally fast. Good job, thank you!
