Different behaviours of Default Argument @Rojo Interesting idea, thank you. In this particular case this solution looks reliable because it is based on documented canonical order. |

Different behaviours of Default Argument @Simon Probably you are right. But how to prevent applying attributes? |

Different behaviours of Default Argument +1. It seems that it is a bug in pattern matcher: defining HoldPattern@f[x_ + y_: 0] := p[x, y] and then evaluating f[a + b] gives p[b, a]. And with f[Unevaluated[Plus[x_, y_: 0]]] := p[x, y] we can create the definition f[x_+(y_:0)]:=p[x,y]. But it also gives p[b, a]. The same is true for definitions f[HoldPattern[Plus[x_, y_: 0]]] := p[x, y] and f[HoldPattern[Plus][x_, y_: 0]] := p[x, y]. |

How to create internally optimized expression for computing with high WorkingPrecision? @Oleksandr RuleDelayed was a typo here, I use Rule both for "Residual" and "Jacobian". |

How to create internally optimized expression for computing with high WorkingPrecision? @Ted Good idea, but I would prefer to optimize the jacobianMatrix once because high precision significantly decreases the number of steps needed to get the minimum: large data set results in large rounding-off errors in summation... |

Exporting PDF file - incorrect graphic Which Mathematica version are you using? There already is one new bug in pdf export introduced in v.9. |

Problem when merging cells including commentary I have no such problem with Mathematica 9.0.1 under Windows 7 x64. |
