@subbu, I'm not sure what you mean. Can you explain in more detail?

comment Accessing the graph Thinning produces without losing all the edges' lengths/slopes
@SvenK, it's an interesting problem. I wonder if the EdgeWeights (i.e. skeleton length in pixels) could be compared to the Euclidean distance between two vertices, to estimate how straight or curvy the line is.

comment How can I prevent ColorFunction from disabling antialiasing in graphics?
The white point moves relative to the black point, like in your picture, and the axes move a tiny bit but don't go blurry. The tick marks get smaller too.

comment How can I prevent ColorFunction from disabling antialiasing in graphics?
I get the same thing (on Windows 7, Mathematica 8.04). The text in e.g. Plot[x,{x,0,1}] is smoothed with ClearType (subpixel rendering), whereas the text in Plot[x,{x,0,1},ColorFunction->(Blue&)] is not. If I turn off ClearType the text in both plots is the same.

@J.M., hopefully one day I'll have a great idea that isn't 40 years too late :-)

To summarise: you are probably better off with kguler's solution!

comment How to do equality check of a large matrix and get the corresponding index position?
@sebastiancheung, the code above works with {n,m} = {5,1000}, but I may have misinterpreted the question. In my code a and b must have the same Length (i.e. same number of rows) so you might need to transpose a. Note that I've compared across rows of b, (i.e. element a[[i,j]] is compared with the elements of b[[i]]). So you might need to transpose b too. I've also assumed that the each row of b is in increasing numerical order. If that's not the case then my approach doesn't work at all.

comment Restricted accumulation of values
HeavisideTheta[0] is undefined, so this has problems if the total reaches zero.

For a half life of 24 hours you should be using Exp[-Log[2] h/24]

@YvesKlett, yes that's normal. You can change the behaviour with WindowFloating->False.

@belisarius, thanks. I'm not clear on what your code snippet gives that Notebooks[] doesn't?
