Francisco M. Garcia

make sur you handle the case where the argument of log is 0. The function is undefinedfor that value

Saeedeh Rezaee

thanks for ur answer

can i solve this problem with changing the number of states?

Edielson Prevato Frigieri

The problem probably is in log argument that is 0, as told Garcia. If you have access to the HMM code, you can change the result, when the argument is 0, to a maximum value. It could help.
