Hi Nasos,<br><br>the implementation looks very promising. A few quick thoughts before going to work today:<br><br>&gt; &quot;automatic&quot; choice seems to be dangerous to me.)<br><br>it is kind of dangerous but this is what most of the people expect. Maybe another &quot;marker&quot; could help but it means overloading 2 operators, like for example mat &lt;&lt; 1 ,2 ,3 % 12,14,16 % 33,44,55;  So that the code will not be too much verbose.<br>
If I remember the operator &amp; is used in LateX to separate lines in array ? (don&#39;t remember exactly). But that would be a &quot;common&quot; sign for users. I&#39;m always in favour of simple writings when developing numerical code.<br>
That&#39;s all cosmetic of course: you can even think about wrting stuffs like <br><span style="font-family: courier new,monospace;">mat =</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">1 | 2 | 3 ||</span><br>
<span style="font-family: courier new,monospace;">6 | 5 | 4 ||<br></span><span style="font-family: courier new,monospace;">7 | 8 | 9;</span><br><br><img goomoji="360" style="margin: 0pt 0.2ex; vertical-align: middle;" src="cid:360@goomoji.gmail"><br>
<br>&gt; - Where do you think this should be added? As a separate header file, or included in vector_ and matrix_ expression headers?
<br><br>Better to have this function attached directly to vector_ and matrix_. One thinks about its immediate availability when programming.<br><br>I will need some examples to write the documentation to all of that too and include it with the one I&#39;m writing right now.<br>
Anyway, that all sounds very good and nice.<br>Thanks.<br><br>David<br clear="all"><br>-- <br>David Bellot, PhD<br><a href="mailto:david.bellot@gmail.com">david.bellot@gmail.com</a><br><a href="http://david.bellot.free.fr">http://david.bellot.free.fr</a><br>
