The following Matlab project contains the source code and Matlab examples used for qsum & qdot compute quadruple precision sum & dot product, fpsum & fpdot give almost full double. .
This small package computes sums and dots product using quadruple precision accumulation or such that allmost full double precision is achieved whatever the condtion number of the computation may be.
