<p class="MsoNormal">Thanks for opening the discussion on this
“new user”-related topic, this is always good to improve our
help for existing user and new comers ; to let them havie a
clear understanding of Scilab-lingua.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One important point to me is to have a
proper distinction between “array” (as values organized in
multiple dimensions) and more precise terms with more
constraints on dimensions “horizontal vector”, “matrix”, etc…
For keeping the rationale up to date, I suggest you to edit
the Localization wiki page [1].<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In term of code update, I can help you
finding duplicated messages but keep in mind that the
build-system create .pot files from the source code. To look
for duplicate, the more important is to upgrade the source
code.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Note: AFAK the “constant” term has been
removed on 6.0.0 documentation/error message as this is the
default datatype, in case of advanced type management the term
“decimal” can be used instead.</p>
</div>
</blockquote>
<p>I think that the "decimal" term has to be discussed. In no way
the default number type in Scilab is decimal
(<a class="moz-txt-link-freetext" href="https://en.wikipedia.org/wiki/Decimal">https://en.wikipedia.org/wiki/Decimal</a>). Scilab actually displays
rounded decimal approximations but internally they are IEEE754
double-precision floating point numbers. I think that the
"floating point numbers" instead of "decimal" would be more
suitable as is does not make any mention of the basis. As far as I
am concerned, I don't have any problem with <br>
</p>
<p>"array of floating point numbers"<br>
</p>
<p>In some contexts, typically when describing the type of arguments
in the documentation of functions, we could be more precise by
making reference to the actual internal object type, i.e. "double"
or "Double", i.e.</p>
<p>array of type double<br>
array of double<br>
</p>
<p>Scilab users are mature enough to accept a bit of technical (but
precise) terms. But this is my personal opinion...<br>

<p>Hi Frederico,<o:p></o:p></p>
<p>In almost all other numerical software the object defined
in Scilab by a=zeros(3,3,3) is called an "array",
m=zeros(3,3) a "matrix" and x=zeros(1,3) or y=zeros(3,1)
"vectors", and all of them are called "arrays". BTW, now the
"hyper" prefix sounds like when it is used in
"hyperspace"... To me, the documentation should be revamped
to always use "array" when the denoted object can have any
number of dimensions and use "matrix" only when the array
has to be a matrix. Concerning your remark about the
"constant vector or constant matrix", yes, this should be
changed by something more explicit, like "array of double".
We already use similar terms in error messages, i.e.<o:p></o:p></p>
<p>"%s: Wrong type for input argument #%d: A matrix of double
expected.\n"<o:p></o:p></p>
<p>Hence we could synchonize the uses of localized messages
with the documentation. When I say "we" it also includes
"you", Frederico. If you feel that Scilab could be improved
by a better documentation, please contribute. If you need
some help to start using the relevant tools (git,
codereview) I would be glad to help you.<o:p></o:p></p>

</span><span style="font-family:"Courier New"">Dear
all,<br>
<br>
In an old script where I needed to apply log10 to an
hyperarray I had implemented it as log(A)/log(10) with a
comment indicating that in that version log10() didn't
work for hyperarrays (unfortunately
</span>I <span style="font-family:"Courier
New"">don't recall what version it was).<br>
<br>
In Version 6.1.0 it does work for hyperarrays, but the
documentation still says that it applies to vectors or
matrices:<br>
<br>
</span><a

style="font-family:"Courier New"">https://help.scilab.org/docs/6.1.0/en_US/log10.html</span></a><span
style="font-family:"Courier New""><br>
<br>
In some contexts "matrix" may be interpreted as an
hyperarray or hypermatrix (for instance when speaking of
N-D matrices), but for Scilab a matrix is formally a
two-dimensional array:<br>
<br>
</span><a
href="https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/help.scilab.org/docs/6.1.0/en_US/matrices.html"

style="font-family:"Courier New"">https://help.scilab.org/docs/6.1.0/en_US/matrices.html</span></a><span
style="font-family:"Courier New"">
<br>
<br>
I think the documentation should indicate that it
applies to vectors, matrices and hypermatrices<br>
<br>
Another problem is regarding log(). It says that the
input argument is a "constant vector or constant
matrix":<br>
<br>
</span><a
href="https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/help.scilab.org/docs/6.1.0/en_US/log.html"

style="font-family:"Courier New"">https://help.scilab.org/docs/6.1.0/en_US/log.html</span></a><span
style="font-family:"Courier New""><br>
<br>
However, it seems that "constant" has a specific meaning
in Scilab as a predefined variable:<br>
<br>
</span><a
href="https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/help.scilab.org/docs/6.1.0/en_US/section_421ab29126e21a1e1e403ee27a18fda4.html"

style="font-family:"Courier New""><br>
<br>
As it is worded, it seems that log() is applied to
predefined variables. I think it should refer more
clearly to the type double (it doesn't work, for
instance, for integer types such as int16(2)).<br>
<br>
In the case of log2() the description of arguments is
even stranger:<br>
<br>
</span><a
href="https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/help.scilab.org/docs/6.1.0/en_US/log2.html"
moz-do-not-send="true"><span
style="font-family:"Courier New"">https://help.scilab.org/docs/6.1.0/en_US/log2.html</span></a><span
style="font-family:"Courier New""><br>
<br>
It confuses the argument section with the description,
and it specifies decimal numbers which isn't a
recognized type.<br>
<br>
The function exp(), on the other hand, doesn't indicate
an output argument.<br>
<br>
I think these functions are very similar and their
documentation pages should be consistent with one
another<br>
<br>
