Function Documentation

CrossCorrelationEvaluationHelperValues gmx::anonymous_namespace{densityfit.cpp}::evaluateHelperValues ( DensitySimilarityMeasure::density  reference,
DensitySimilarityMeasure::density  compared 
)

Calculate helper values for the cross-correlation.

Enables numerically stable single-pass cross-correlation evaluation algorithm as described in Bennett, J., Grout, R. , Pebay, P., Roe D., Thompson D. "Numerically Stable, Single-Pass, Parallel Statistics Algorithms" and implemented in boost's correlation coefficient
