how do we get adjacent values of an element in a 2D array matrix

for example, the matrix is A[6 4 9 7 3 1; 4 8 1 9 3 8; 3 8 5 7 3 9; 8 2 4 6 3 7]

my current location is A[4,3]=4 and i want to get the adjacent elements [7;6] how would i write this code,

and also if i was at the location A[1,5]=3 how would i get the adjacent elements of it

thanks

I told you how in your duplicate post https://www.mathworks.com/matlabcentral/answers/355657-how-do-i-make-a-for-loop-picking-out-adjacent-values-of-an-2d-array#comment_482824

if i want to start at one end, for e.g A[1,1], what code would i have to write to elevate all the way till end of column

[rows, columns] = size(A)
for col = 1 : columns
    thisColumn = A(:, col);
    % Now do something with thisColumn......
end
