<br>
The code was just missing many dots (* => .*, ^ = .^), to make
operators working in an elementwise way (see attachement).<br>
Fixing that makes the expected picture:<br>

This could make a nice demo, in the <i>Graphics => More
surfaces</i> section.<br>

<div>Hello all,</div>
<div><br>
</div>
<div>I have been testing the latest version of Scilab (6.0.1)
and have been looking at data visualisation of
non-orientatable surfaces (e.g. Moebius, Klein Bottle etc.).</div>
<div><br>
</div>
<div>The Moebius strip was not hard to figure out, but I am
having issues with the Klein Bottle.I have attched the code as
is so far, uses the parametric equations from <a
moz-do-not-send="true"
href="https://en.wikipedia.org/wiki/Klein_bottle">https://en.wikipedia.org/wiki/Klein_bottle</a>,
for the 3D immersion of the bottle.</div>
<div><br>
</div>
<div>As a test, I used the old software Derive 6 to run the
equations and it plots the bottle as correct. If anyone has
pointers on this code that would be helpful.</div>
<div><br>
</div>
<div>Still learning Scilab!</div>
<div><br>
</div>
<div>Thanks</div>
