Reproducing code:

    float ha[] = {1,
                  101, 102, 103, 104, 105,
                  201, 202, 203, 204, 205,
                  301, 302, 302, 304, 305,
                  401, 402, 403, 404, 405,
                  1010, 1020, 1030, 1040, 1050,
                  2010, 2020, 2030, 2040, 2050,
                  3010, 3020, 3030, 3040, 3050,
                  4010, 4020, 4030, 4040, 4050};
    {
        af::array aa(sizeof(ha) / sizeof(float), ha);
        af::array aa0 = aa(af::seq(1, af::end));
        af::array aa1 = af::moddims(aa0, 5, 4, 2);
        af::array aa2 = aa1(af::seq(3), af::seq(3), af::span);
        af_print(aa2);
    }

output:

aa2
