%% Largest Element in Matrix
% Create a matrix A and use its column representation, A(:), to find the value and index of the largest element.

A = [8 2 4; 7 3 9]

%

A(:)

%

[M,I] = max(A(:))

% I is the index of A(:) containing the largest element.
%
% Now, use the ind2sub function to extract the row and column indices of A corresponding to the largest element.

[I_row, I_col] = ind2sub(size(A),I)

%
% If you need only the maximum value of A and not its index, then call the max function twice.

M = max(max(A))
