Vector functions[edit]

Why isn't there a link like ■—›Rn for vector functions? Freeboson {talk | contribs} 19:06, 16 July 2013 (UTC)

Maybe, because a vector space is not necessarily a real vector space? Of those Rn represents only a partial (finite-dimensional) case, indeed. I do not know where to push the link vector-valued function and I am not certain the scope of the article. Incnis Mrsi (talk) 20:06, 16 July 2013 (UTC)
I think you might have misunderstood what I meant. In the template, on the left, we have, e.g. ■—›R—›■, where the first mapping is a real-valued function and the second mapping is a function of a real variable. On the right however, we only have Rn—›■, i.e., functions of several variables. I was just wondering why we didn't have instead ■—›Rn—›■: vector-valued functions, and then functions of several variables. The real case is just an example.

To your other point, I would suggest that all of the links for both ■—›Rn, and ■—›Cn go to the same page vector-valued function. Freeboson {talk | contribs} 21:09, 17 July 2013 (UTC)

Missing characters[edit]

Lots of little boxes (presumably missing characters) in the display of this template for me (FF 17.0.9 on Gentoo Linux):

—› B Bn —› B
—› Z —›
—› R —› Rn —›
—› C —› Cn —›

(I have replaced the boxes in the original template with the U+25A0 BLACK SQUARE character for the table above.)

Are others seeing these boxes in the original template? I ask because when I copy-and-paste the characters from the template's wiki source into Wiktionary searches, they all led to the entry for that same Unicode character! This is unlike other cases where I'm simply missing the character on my computer (in which case, a Wiktionary search will reveal what characters are actually being used).

If other people are seeing different (meaningful) characters in the original template, what font do they rely on, and are there alternatives we can use that are more widely supported? - dcljr (talk) 03:30, 25 August 2014 (UTC)

Wait a minute... Is this intentional? Are the boxes supposed to represent an "arbitrary set"? If so, we really should probably just use "X" and not a special Unicode character. - dcljr (talk) 03:32, 25 August 2014 (UTC)
