I have a matrix Z that is (5,6) and I would like to circshift only its odd rows by 1. Any advice on how that can be done? Thanks!

Trivially?

A = magic(7)

A =
    30    39    48     1    10    19    28
    38    47     7     9    18    27    29
    46     6     8    17    26    35    37
     5    14    16    25    34    36    45
    13    15    24    33    42    44     4
    21    23    32    41    43     3    12
    22    31    40    49     2    11    20

A(1:2:end,:) = circshift(A(1:2:end,:),1,2)
A =
    28    30    39    48     1    10    19
    38    47     7     9    18    27    29
    37    46     6     8    17    26    35
     5    14    16    25    34    36    45
     4    13    15    24    33    42    44
    21    23    32    41    43     3    12
    20    22    31    40    49     2    11
