title: Is there a Python equivalent of MATLAB's conv2 function?
body: <p>Does Python or any of its modules have an equivalent of MATLAB's <a href="http://www.mathworks.com/help/techdoc/ref/conv2.html" rel="noreferrer">conv2</a> function? More specifically, I'm interested in something that does the same computation as <code>conv2(A, B, 'same')</code> in MATLAB.</p>
