Translating MATLAB's cell2mat into Mathematica @SjoerdC.deVries Yes, that's my point, it is not mma syntax and not intended to. It puts the onus on the answerer. |

Translating MATLAB's cell2mat into Mathematica @SjoerdC.deVries well {[1], [2, 3, 4];[5; 9], [6, 7, 8; 10, 11, 12]} isn't a valid Mathematica expression. The current answer basically takes an arbitrary (as far as I can tell) interpretation of the question and answers that; that's OK and I upvoted it, but it still doesn't make the question as it is clear. Perhaps the OP could modify the question so that the current answer is actually an answer to it, since they've indicated that this is what they want. |

Efficient evaluation of function defined by multiple Sum Without looking at the code in detail, did you try replacing Sum[...,{}] by Total@Table[...,{}]? |

Fitting data without an equation add the option Joined->True and possibly PlotMarkers->Automatic to ListPlot |

Dynamic List Building and Exporting I guess my point is, it's not clear what the problem is. You have a bunch of lists, just make them strings, join them, with line breaks at the right place and export them. Is that what you don't know? |

Dynamic List Building and Exporting you can create a list of the list1x, list2x etc lie this: NestList[
# + .5 &,
{1, 1.1, 1.2, 1.3, 1.4},
5
]. You didn't say how list1 etc are to be created. You can output all these with Export (which is described in the docs and lots of places here) |

How can I compile this function one problem is Tuples, see On[Compile::exttensor]; Compile[{{x, _Real, 1}}, Tuples[x, 2]]. It's not compilable. |

Creating list within function put a ; after the closing bracket of the For loop. As it is you are returning tempData multiplied by the value returned by For[], which is Null |

How to programmatically comment out multiple source files? you can just read the file in as a string, prepend and append the appropriate characters and save it back |

Why are these flow lines cut short? Could you explain what you mean by "slope field"? Preferably without using bundles for the pedestrians among us. |

What is the correct way to use NIntegrate inside the FindMinimum function? maybe a.Table[alpha[t, i, h], {i, 1, n - 1}] isn't the best way to go here. |

Which integration strategy to use for this product of polynomials? OK I see, I had interpreted this to be about Integrate; with the clarification it's unambiguous. |

Which integration strategy to use for this product of polynomials? What do you mean by "integration strategy"? (I mean, what are you really asking? how to construct the arguments of Integrate[]?) I imagine you need this analytically, right? |

How can I name “a[[i]]” the parts of Table “a”? Or how to make Table “a” grow inside FindMinimum? +1; I did not know this syntax was valid. |
