What do you mean by &quot;summarize&quot;?<br>If for instance you want to sum along Y, just do<br>  my_array.sum(axis=1)<br><br>-=- Olivier<br><br><div class="gmail_quote">2012/1/20 Ruby Stevenson <span dir="ltr">&lt;<a href="mailto:ruby185@gmail.com">ruby185@gmail.com</a>&gt;</span><br>

Say I have a three dimension array, X, Y, Z,  how can I condense into<br>
two dimensions: for example, compute 2-D array with (X, Z) and<br>
summarize along Y dimensions ... is it possible?<br>
<br>
thanks<br>
