<font color="#ff0000" face="arial, helvetica, sans-serif" size="1"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"></span></font>I think the error comes from the fact that
<i>source<span class="gmail_default" style="font-family:arial,helvetica,sans-serif">model</span>.inside</i> is a 3-dimensional logical array<span class="gmail_default" style="font-family:arial,helvetica,sans-serif">. The operation -
<span style="color:rgb(255,0,0);font-size:x-small">any(cfg.grid.inside>1)</span> does not output a logical scalar value because<i> sourcemodel.inside</i> is in 3 dimensions. </span>
<div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">So far I have always worked with models whose inside parameter was of one dimension. Anyway, I'm not sure if this is the problem, please correct me if I'm wrong.</span><font color="#ff0000" face="arial, helvetica, sans-serif" size="1"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"></span><br>
