<p>Dear All</p>
<p>I'm looking in a way to reshape a 2D matrix into a 3D one ; in my example I want to<span> </span><span><strong>move the columns from the 4th to the 8th in the 2nd plane</strong> </span>(3rd dimension i guess)</p>

<p>a = p.reshape(d, (2,5,4), ) but it is not what I'm expecting</p>
<p><br></p>
<p>Nota : it looks like the following task (while I want to split it in 2 levels and not in 4), but I've not understood at all</p>
