Abstract

A detailed description of an algorithm for the effective bit test in noncoherent conditions is presented. This algorithm offers reasonable convergence and accuracy advantages over existing methods. A flow diagram for the algorithm and its implementation using the MATLAB package is included. The metrological reliability of input data is checked. An adopted ZEROIN program and Householder orthogonalization are applied to estimate the starting point of an iterative process, and the Newton´s method is involved in a final calculation for the best-fit curve to the input data
