logsumexp
Description
Provides two traits:
LogAddExp, which provides a numerically stable evaluation ofln(exp(a) + exp(b)), utilizingln_1p_expfrom thelnexpcrate. Implementations are provided for forf64andf32(and their respective references).LogSumExp, which provides a numerically stable, 1-pass (online) algorithm for evaluation of LogSumExp with correct handling of +/- infinity andnan. Implementations are provided iterators which produceItems off64orf32(and for respective references).
