How do I sum over a dimension in array while dropping the traversed dimension?
<p>I want to do a sum over one dimension in an array. That's easy. For an array 9x100x100:</p>

<pre><code>sum(a,1)
</code></pre>

<p>However what is then left is an array with dimension 1x100x100. And now I want to get rid of the first dimension, since there is only one element left. So my solution is just:</p>

<pre><code>reshape(summed_array, 100,100)
</code></pre>

<p>In order to get the 100x100 array, which I wanted.
However this does not feel very clean. Is there a better way of achieving this?</p>
