<hr><pre>Hi,<br><br>Using scilab 4.1 on NetBSD/i386 4.0.1, I'm trying to plot an ellipse with <br>equation (x^2/9) + (y^2/4) = 1. However, I get the error "inconsistent <br>addition" which seems to be related to "+" and everything behind it: <br>

<br>plot(((x**2)/9)+((y**2)/4)=1)<br><br>(I made a snapshot, but Pan seems unable to insert it.) What is the <br>reason for the error?<br><br>Thanks for helping out.<br><br>Huub<br><br></pre>
