matlab隐马尔可夫简单例子实现

%参考：matlab help 文件
%例子中：状态变量为离散分布，值域为{‘fair‘,‘loaded‘};观测变量为离散分布，值域为{‘one‘,‘two‘,‘three‘,‘four‘,‘five‘,‘six‘}
tr = [0.95,0.05;                            %状态转移矩阵 [2x2]
      0.10,0.90];
            
e = [1/6,  1/6,  1/6,  1/6,  1/6,  1/6;     %发射矩阵的维度 o=b‘*i; [6x1]=[6x2]‘x*[2x1];
     1/10, 1/10, 1/10, 1/10, 1/10, 1/2;];    
 
[seq, states] = hmmgenerate(100,tr,e);      %100个时间序列单元

% [seq, states] = hmmgenerate(100,tr,e,‘Symbols‘,...    %设置隐变量2个可能取值的名称和观测变量6个可能取值的名称
%           {‘one‘,‘two‘,‘three‘,‘four‘,‘five‘,‘six‘},...
%            ‘Statenames‘,{‘fair‘;‘loaded‘}
