Obtaining better quality in ListPlot with this approach what you need to do is increase imagesize and add scaling code to the postscript output to scale it back down to fit the page. This will effectivly shrink everything, points, lineweights, etc. |

Efficiently compute double sum this seems a miniscule bit faster..: Flatten[ Table[ m[[i]] n[[j]] , {i, n1}, {j, n2}] ].Flatten[Table[f[t[[i]],z[[j]]], {i, n1}, {j, n2}]]. |

Obtaining better quality in ListPlot Perhaps some system dependacy? On linux export to EPS produces a real vector eps file with no preview. The file size is essentilaly unchanged if you vary ImageSize. |

intersection between two curves in Mathematica do you need an approach that works with tabular data or can you use the actual function? If you interpolate the tabular data you of course end up with an approximate solution. I only see one curve in your example by the way. |

Represent Plot Scale with an offset IT might be simpler for you to explicitly put in the ticks you want. Ticks->{{{0,0},{50,5},{100,10},{{0,0},{100,10}},{{400000,40000},{500000,50000}}} Lookup Ticks[] in the manual if you dont understand |

Represent Plot Scale with an offset In some cases its simple to just change the data.. Plot3D[0.1 Sin[(10 x) (10 y)], {x, 0, .4}, {y, 0, .4}, Mesh -> None] should achieve the same.. Of course its often not so simple.. |

MiniMaxApproximation after loading the package you will find minmax doesnt like it when you request a numerator of the same order as the polynomial expressions,..x^2, {x , {8,10},1,2} works |

What algorithm does Plot use to determine abscissas? a more interesting varient on belisarius suggestion: ListPlot[Reap[Plot[Sow[x]; 1/(x - .5)^2, {x, 0, 1}]][[2, 1]]]. You can see that there is an adaptive curvitue based algorithm. Oddly it seems to never eval at the lower bound.. |

Find all the last weekends in a year It might be cleaner to just find last Saturday or last Sunday, depending on how you mean to handle the wrap around weekends. |

Saving graph as a .ps file without legend "Mathematica for Students gives you all of the functionality of the standard version for a low price." What is it $150? Do they tell you about this feature before you buy? |

Ignore missing data while doing a Mean interesting, this effect of an empty Sequence[] seems to be undocumented. Learn something new every day. |

Ignore missing data while doing a Mean in a nutshell convert the list of 2x2 matrices to a 2x2 matrix of lists of the individual components. Use select on each component list to drop non-numeric values, then take the mean. |

Import a file only if it contains a certain pattern If its a large file with tag info at the beginning you might want the do raw open/read operations to get the key you need, then import only as needed. For small files my guess is you are just as well off to import the whole thing and descard what yuo dont need. |
