stdlib_sum_kahan Interface

public interface stdlib_sum_kahan

Summary

Sum elements of rank N arrays. (Specification)

Description

This interface provides standard conforming call for sum of elements of any rank. The 1-D base implementation follows a chunked approach combined with a kahan kernel for optimizing performance and increasing accuracy. The N-D interfaces calls upon the (N-1)-D implementation. Supported data types include real and complex.
