@rm-rf very good memory for patterns?

@acl Hehe, I do have a good memory for patterns...

@Mr.Wizard I realized something duplicates, sometimes I'll delete my poor questions, do you think that's a answerable question, I undeleted now.

@Mr.Wizard and maybe "MathOutput" -> "InputForm" is the right choice.

@HyperGroups I just took at the question again. At least in version 7 I don't think that does a complete job. I see output, and strangely some input in text form, but I also have much of the input as images (in the exported HTML).

@HyperGroups I find that I don't know much about conversion to HTML as I rarely use it, and things seem to be behaving erratically here; possibly bugs. If you have a solution to your own question and you have tested that it works as you believe in the version that you use I encourage you to post it as an answer.

@Mr.Wizard I found merge several input cells will generate images in htmls.

@HyperGroups Interesting; let me look at that.

@HyperGroups Strange, but that seems to be the case here. It comes as a surprise. Perhaps you could include that with "MathOutput" -> "InputForm" in your self-answer?

@Mr.Wizard. Would you look at this. I am thinking you could cast some further light on the apparent globalization of the dynamic module local variable

@Mr.Wizard Fine, I gave that answer first, and wish someone give a complete answer

@m_goldberg Sorry, I left just as you got here. I'd be glad to give it a look but I probably won't have time to reply tonight, assuming I even have anything useful to say.

hello everyone

Dear all, how to vectorize logical operations in MMA? For example, the code '[1,2,3]<2' will return '[1,0,0]' in Matlab.

@EdenHarder: try Thread[{1, 2, 3} < 2]

@EdenHarder look at this recent Q&A:

Thanks you all

Have you guys know about Nontransitive dice?

I tried Boole[Thread[{1, 2, 3} < ##]] &[2, 5] to get {{1,0,0},{1,1,1}} but failed.

@EdenHarder Try Boole[Thread[{1, 2, 3} < ##]] & /@ {2, 5}

@MichaelE2 Thanks!

any one like to try my demo on finite difference formula? just to make sure it is ok before I send it to WRI? Just need to make sure it runs ok for you, clear and so on.

I define a function f and want to evaluate f at each vector in Permutations[Range[9]] and then find the maximum, is the following code right? Max[f[##] & /@ Permutations[Range[9]]]

@EdenHarder I just read about it on Wikipedia, but what is your code supposed to do?

@EdenHarder Yes, if you want the max. of f[{1, 2, ...}] etc. If you want f[1, 2, ...], then instead of f[##]&, use f @@ #&.

@Calle Thanks all! Michael E2's answer is enough. Good Night!
