## (double* log_a, state* s, hypoList* parent)

Calculates the logarithm of sum(exp(log_a[j,a_pos])+exp(log_gamma[j,g_pos])) which corresponds to the logarithm of the sum of a[j,a_pos]*gamma[j,g_pos]

## Documentation

Calculates the logarithm of sum(exp(log_a[j,a_pos])+exp(log_gamma[j,g_pos]))
which corresponds to the logarithm of the sum of a[j,a_pos]*gamma[j,g_pos]

**Parameters:****log_a** - : transition matrix with logarithmic values (1.0 for log(0))

**s** - : state whose gamma-value is calculated

**parent** - : a pointer to the parent hypothesis

**Returns:**- logSum for products of a row from gamma and a row from matrix A
