Forward-Algorithm.

Documentation

Forward-Algorithm. Calculates alpha[t][i], scaling factors scale[t] and log( P(O|lambda) ) for a given double sequence and a given model.

Parameters:

- smo model
O - sequence
length - : length of sequence
alpha - : alpha[t][i]
scale - : a reference for double type, scale factors
log - \_p: a reference for double type, log likelihood log( P(O|lambda) )

Returns:

0 for success, -1 for error
