function [A] = specialMatrix(n,m)

% It is recomended to first create the matrxix A of the correct size, filling it with zeros to start with is not a bad choice
%--------------------------------------------

end

error('Error: Index error. Arguments must be positive integers or logical values.')
end

% Now the real challenge is to fill in the correct values of A
A(1,:) = 1:m; %Lables the first row with column numbers
A(:,1) = 1:n; %Lables the first column with row numbers
for j = 2:n
for k = 2:m
A(j,k)=A(j-1,k)+A(j,k-1); % fills each element of the matrix with the sum of the left and above element.
