<div class="moz-cite-prefix">Thank you for being open to finding the
right word.</div>

<div class="moz-cite-prefix">For me the plurality is not so
important - but let's say it's the wording used in all our
educational books (in English) ... just dig into any Signal
Analysis book, etc., and what we're trying to name here is exactly
that, then it would be bad for Scilab to give it a different name.
Renaming something that is universally defined otherwise is an
uphill battle we cannot win.<br>

have a purpose. When there's asymmetric windows, then there must
also be symmetric windows.<br>

</font><font face="Courier New">As a general concept, y</font><font
face="Courier New">ou are right ... but with nuances. The
problem is deciding when something is really wrong and when it
is just a question of opinion or personal preference. It is
wrong to say the Earth is flat, no matter how many people say
it. But is it right or wrong to call something just a
conventional name? <br>
<br>
For instance: Is it right to call </font><font face="Courier
New">the derivative of a function </font><font face="Courier
New">"derivative"? Probably not, because "derivative" is a
general concept which seems to have no relationship with its
meaning in math. Probably in its origins it was more related to
grammar than to math. But once established for centuries, it
wouldn't be convenient to change it on the basis that it is
"wrong".<br>
<br>
By the same token, calling "periodic" a window function obtained
from periodic functions (cosines) whose period is equal to its
length doesn't seem intrinsically wrong to me. Calling it
"closed" would be worse since one immediately thinks either of a
closed set, which is not, or a closed curve, which isn't either.<br>
<br>
But even if we found a better word, changing it would very
likely create an unnecessary cognitive dissonance to thousands
or millions of practitioners.<br>
<br>
Anyway, if a much better and cristal-clear word (i.e., whose
meaning would be immediately obvious in its context) were found
and gained consensus, no problem to use it instead of
"periodic". The important thing in my proposal was to include in
the window() function the feature, not how we call it.<br>

Like it or not, I guess these keywords come from Matlab, and as Matlab
still seems to dominate the market, many people, including those
willing to quit Matlab (as I did several years ago), are quite used to
those keywords

If a way of doing is wrong, then just keep on going because "everybody does so" is just an argumentum ad populum
