function[ArrayZ]=SumArray(ArrayG)
A=[1 4 3]
B=[6 8 9]
ArrayZ=[A;B]
S=sum(ArrayZ,1) %%outputs the sum of the colm
S=sum(ArrayZ,2)%%outputs the sum of the row
%%I want to concantinate? to have ArrayZ=[1 4 2 8;
6 8 9 23;
7 12 12 31]
%%How do I merge the array with the sum outputs?
endfunction

I think this is the solution:
S=sum(ArrayZ,1) %%outputs the sum of the colm
ArrayZ=[ArrayZ; S]; %%append the sums
S=sum(ArrayZ,2)%%outputs the sum of the row (included appended new values)
ArrayZ=[ArrayZ, S];

function[ArrayZ]=SumArray(ArrayG)
A=[1 4 3] ; B=[6 8 9] ;
AB=[A;B] ;
S1=sum(AB,1) ;%%outputs the sum of the colm
S2=sum(AB,2) ;%%outputs the sum of the row
ArrayZ = AB ;
ArrayZ(:,end+1) = S2 ;
ArrayZ(end+1,:) = [S1 sum(S2)] ;
end
