Basic usage - links
links={'a1','A',1.2;'a2','A',1;'a1','B',.6;'a3','A',1; 'a3','C',0.5;
'b1','B',.4; 'b2','B',1;'b3','B',1; 'c1','C',1;
'c2','C',1; 'c3','C',1;'A','AA',2; 'A','BB',1.2;
'B','BB',1.5; 'B','AA',1.5; 'C','BB',2.3; 'C','AA',1.2};
% Create a Sankey diagram object
% 创建桑基图对象
SK = SSankey(links(:,1), links(:,2), links(:,3));
% Start drawing
% 开始绘图
SK.draw()
Basic usage - adjMat
% Define inter-layer adjacency matrices
% 定义层间邻接矩阵
A12 = [1,2,1; 1,2,3; 2,0,1];
A23 = [1,4; 2,1; 0,3];
A34 = [1,5; 2,3];
% Assemble global block matrix (main diagonal = zero, super-diagonal = A12, A23, A34)
% 组装全局分块矩阵（主对角线为零，上对角线为 A12, A23, A34）
adjMat = mergeAdjMat({A12, A23, A34});
SK = SSankey([],[],[], 'AdjMat',adjMat);
SK.draw()
The compressed package contains numerous usage examples.
