Working...

[Justace C. <pro...@co...>]

Cool,

	My stuff is almost working and with the image patch much faster.  The
new deal is this.  Since I am generating a correlation matrix with
respect to one set of channels, i.e.  the channels correlated with
themselves, half of the matrix is useless.  Specifically the upper left
of the diagonal.  So, to cut back on my calculation time I fill that
region with NaN, but how do I put that in gnuplot so that it does not
plot it?  I was putting it in as a -2 and then telling it to only plot
[-1:1] on the z but that was silly since it is a 2D plot.  Maybe the
image style needs to have an internal variable that the user can set to
define NaN's.  That way I could go and set that to -2 and when image
converts the float to a color it goes ohhh this is a NaN, what fill
style should I use here or what predefined color do I have for NaN. 
Just some thoughts and questions here.
