comment Problem with the DSolve function
@LazarosM. Actually its [[1, All, 2]]. It's short for Part and it's about getting the solutions in a list for plotting

comment How to write values of function to file?
Well, that depends: do you want equal spacing of points, or do you want to make use of mathematica's adaptive sampling?

Amm x=0 and y=0 is a line (ie. intersection of two planes). Or did you want to plot two planes.

comment Is it possible to construct a function to make a poor man's Mathematica database?
It's probably much better to go with a real database. Having said that, perhaps you could use Leonid's SQL DSL as a starting point and just operate on mathematica lists, which you could export to a file.

comment exporting list of matrices in mathematica
Yes, I know, but I had 100 MB mx files laying around, and just adding ".gz" reduced the file size 3-4 times, while not noticeably hindering the speed of loading.

comment exporting list of matrices in mathematica
I'm using Export["data.mx.gz",data] which I think is a good compromise between files size and the speed of loading.

Any reason why you prefer Union over DeleteDuplicates?

comment Creating a graph with variable size of vertices and variable thickness of edges
Thanks! Got something which is quite OK. Are there any options to make the edges go around vertices (like in LayeredGraphPlot)? But this should probably be a whole new question then ;)
