Constructors

The hmm plugin has two different constructors:

hmm( )
hmm( $<$N$>$, $<$M$>$ )

where the first one creates an empty hidden Markov model with $0$ states and $0$ observation symbols (it assumes its parameters will be loaded hereafter); and the second one creates a HMM with $<$N$>$ hidden states and $<$M$>$ observation symbols, and initializes its parameters with random values, satisfying the stochastic constrains. Each of the $N$ states is associated with a unique integer number, ranging from $0$ to $N-1$, which identifies the state. The same is true for the observation symbols. Each of the $M$ symbols is represented by a unique integer number, whose value can range from $0$ to $M-1$.
