[Matplotlib-users] getting slices out of an array

[Olivier B. <Oli...@id...>]

Hello all,

I'm converting some matlab scripts to matlibplot, and I don't know how
to make some "slicing" efficently with matlibplot. What I want to do is
to translate a matlab code like:

    x =3D [[01, 02, 03, 04, 05, 06];
         [11, 12, 13, 14, 15, 16];
         [21, 22, 23, 24, 25, 26];
         [31, 32, 33, 34, 35, 36];
         [41, 42, 43, 44, 45, 46];
         [51, 52, 53, 54, 55, 56]
         ];
    x(2:4,1:4)
   =20
    ans =3D
   =20
        11    12    13    14
        21    22    23    24
        31    32    33    34
   =20
What I have done now in matplotlib is like:

    x =3D array ([[01, 02, 03, 04, 05, 06],
                [11, 12, 13, 14, 15, 16],
                [21, 22, 23, 24, 25, 26],
                [31, 32, 33, 34, 35, 36],
                [41, 42, 43, 44, 45, 46],
                [51, 52, 53, 54, 55, 56],
                ])
    for i in range (3):
        for j in range (4):
            x2 [i][j] =3D x [i+1][j+0]

so, x2 is now what I want:
    [[11,12,13,14,]
     [21,22,23,24,]
     [31,32,33,34,]]

I will be very happy to make the "slicing" without the loop...
I'm pretty new to matlibplot, so sorry if this is a too simple question.

Thanks in advance for your help.

        Olivier
