::: I did see them. For {{tmpl|tcllib}}, I made the target component be a string SMW property instead of a page (using the parameter to {{tmpl|property}} on the property's page), which makes sense anyway since I don't plan to make a page for every component package in Tcllib (too damn many; CPAN would have the identical problem). Or were you talking about something else and I've misunderstood? :-) –[[User:Dkf|Donal Fellows]] 22:15, 25 November 2010 (UTC)
:::: I got a similar maintenance reaction for Java. I wonder if there's a way to automate that kind of maintenance, or toggle the page/string option. Maybe {{tmpl|uses from}} should use the string property instead. --[[User:Short Circuit|Michael Mol]] 22:26, 25 November 2010 (UTC)
To be clear, this is also called [[wp:linear interpolation]]. --[[User:IanOsgood|IanOsgood]] 17:39, 30 November 2010 (UTC)

When I wrote this task, I was just looking to write the linear mapping function. I'm not sure that explicit test samples from the source and destination sets are appropriate; I think that will reduce the effectiveness of languages which are likely to graph their results, like Maple, Octave or Mathematica.--[[User:Short Circuit|Michael Mol]] 14:46, 26 November 2010 (UTC)
:Any idea of how to re-write this to allow graphing an answer? (I don't regularly use graphing tools). --[[User:Paddy3118|Paddy3118]] 16:43, 26 November 2010 (UTC)
:: It's just a kind of program output. The real problem I was touching on, I think, was that one couldn't demonstrate using a contiguous function. I loosened the task requirements again, so that should be doable. --[[User:Short Circuit|Michael Mol]] 22:17, 26 November 2010 (UTC)
I'd like to see a related task which performs a nonlinear mapping. (I hadn't thought of the nonlinear case when I wrote the task.) Specifically, an arbitrary one, where an <math>f(x)</math> can be provided to define the...distribution? For example, if <math>f(x)=x</math>, the numeric result would be the same as with this task. --[[User:Short Circuit|Michael Mol]] 14:46, 26 November 2010 (UTC)
: In other words, given maprange function g, and arbitrary function f, compute g(f(x))? --[[User:Rdm|Rdm]] 14:59, 26 November 2010 (UTC)
:: I suppose so, yeah. That would handle the analogous cases I could think of. (converting a linear 16-bit PCM input to, e.g. 8-bit a-law or <math>\mu</math>-law.) --[[User:Short Circuit|Michael Mol]] 22:17, 26 November 2010 (UTC)
