%% sankey demo0 : Basic uasge - equivalent code

%% Basic usage - links
figure('Name','sankey demo0-1','Units','normalized','Position',[.05,.2,.5,.56])
% Define links
links={'a', 'A', 3; 'a', 'B', 1; 'a', 'C', 1; 
       'b', 'A', 1; 'b', 'B', 5;
       'c', 'B', 2; 'c', 'C', 4;
       'A', 'AA', 4; 'A', 'CC', 1; 
       'B', 'BB', 5; 'B', 'CC', 3; 
       'C', 'AA', 5};

% Create a Sankey diagram object (创建桑基图对象)
SK1 = SSankey(links(:,1), links(:,2), links(:,3));

% Set node order and layer (设置节点顺序及层次)
SK1.NodeList = {'a', 'b', 'c', 'A', 'B', 'C', 'AA', 'BB', 'CC'};
SK1.Layer = [1, 1, 1, 2, 2, 2, 3, 3, 3];

% Start drawing (开始绘图)
SK1.draw()


%% Basic usage - adjMat
figure('Name','sankey demo0-2','Units','normalized','Position',[.05,.2,.5,.56])
% Define inter-layer adjacency matrices (定义层间邻接矩阵)
A12 = [3,1,1; 1,5,0; 0,2,4];   % a,b,c -> A,B,C
A23 = [4,0,1; 0,5,3; 5,0,0];   % A,B,C -> AA,BB,CC

% Assemble global block matrix (组装全局分块矩阵)
% main diagonal = zero, super-diagonal = A12, A23 (主对角线为零，上对角线为 A12, A23)
adjMat = mergeAdjMat({A12, A23});

SK2 = SSankey([], [], [], 'AdjMat',adjMat);

% Set node names (设置节点名称)
SK2.NodeList = {'a', 'b', 'c', 'A', 'B', 'C', 'AA', 'BB', 'CC'};

SK2.draw()
