Slicing of a NumPy 2d array, or how do I extract an mxm submatrix from an nxn array (n>m)?
...can do it with basic slicing:
In [49]: x=np.arange(16).reshape((4,4))
In [50]: x[1:4:2,1:4:2]
Out[50]:
array([[ 5, 7],
[13, 15]])
This returns a view, not a copy of your array.
In [51]: y=x[1:4:2,1:4:2]
In [52]: y[0,0]=100
In [53]: x # <---- Notice x[1,1] has changed
Out[53]:
