Numpy array - duplicating rows and centering columns in a larger array
<p>I have a large number of arrays with dimension 72, x where x is less than 144. I'd like to take these arrays and do two things to them:</p>

<ol>
<li><p>Duplicate each row in the original so that there are 144 of them.</p></li>
<li><p>Center the arrays horizontally inside a larger 144</p></li>
</ol>

<p>The end result is a 144x144 array. I'd like to use numpy and to the greatest extent possible avoid loops ( I can already implement this in loops ). I've searched around but haven't found a neat solution yet.</p>

<p>Thanks,</p>
