Consider you have number of rows and columns which is an even number,
Odd rows:
A1(1:2:end-1,:)
Even rows:
A1(2:2:end,:)
Odd columns:
A1(:,1:2:end-1)
Even columns:
A1(:,2:2:end)

By substracting one, you discard the last odd row (column) when the number of rows (columns) of the array is odd. When this number is even, it does not matter, so just to be flexible, do not subtract one :)

Yes you are right Jos, therefore at the beginning of the question, I stated that:
Consider you have number of rows and columns which is an even number
