Talk:Step function

Step change

I have removed the re-direct and given 'step change' an entry of its own. This is worth doing because the phrase is being adopted by the political propaganda people and the rest of us need to know what they are trying to say so that we can ignore them in peace. 82.38.97.206 08:33, 24 December 2005 (UTC)mikeL

Sounds good, thanks. It is more appropriate that way than having that text in step function. Oleg Alexandrov (talk) 17:09, 24 December 2005 (UTC)

Half-open intervals

The current definition has all the intervals closed on the left and open on the right, but surely that isn't a necessary part of the definition? --ScottAlanHill 14:23, 18 June 2006 (UTC)

I agree. I guess one should mention that somehow. Oleg Alexandrov (talk) 16:19, 18 June 2006 (UTC)

Staircase function

The lemma staircase function is a redirect to step function. However, this name does not appear in the article at all. Question: is this an equivalent synonym? --85.179.52.216 09:50, 27 June 2007 (UTC)

Recent change

I removed the assumption that a step function must necessarily use half-open intervals. The function $\chi _{[0,1]}$ is an honest step function, for example. Also, I modified the notation $1_{A}$ to $\chi _{A}\,$ which I think reads better. Oleg Alexandrov (talk) 22:31, 26 May 2008 (UTC)

Delete and redirect.

Bullshit.

When people say step function, they mean Heaviside step function.

Either find some real references-- not just Wolfram-- or, better delete this article and make it a redirect. Geoffrey.landis (talk) 01:09, 14 May 2020 (UTC)

Search on Google for the meaning of a Step Function.

Don't get frustrated because the books you've read are unclear and don't use the full name of the function. Anderson Pozzi (talk) 17:22, 23 June 2024 (UTC)
