用Viterbi算法来解码隐马尔科夫模型(HMM)的状态变量。其中，mainfile_Vit.m是主函数，Viterbi_algorithm.m是调用的Viterbi算法函数。-Viterbi algorithm for decoding the hidden states of the Hidden Markov Model(HMM). In this folder, "mainfile_Vit.m" file is the main function, and "Viterbi_algorithm.m" file is Viterbi algorithm function to be called.
