MORE ON VOLTAGE-PROCESSING TECHNIQUES 14.1 COMPARISON OF DIFFERENT VOLTAGE LEAST-SQUARES ALGORITHM TECHNIQUES Table 14.1-1 gives a comparison for the computer requirements for the different voltage techniques discussed in the previous chapter. The comparison includes the computer requirements needed when using the normal equations given by (4.1-30) with the optimum least-squares weight W given by (4.1-32). Table 14.1-1 indicates that the normal equation requires the smallest number of computations (at least when s m, the case of interest), followed by the Householder orthonormalization, then by the modified Gram–Schmidt, and finally the Givens orthogonalization. However, the Givens algorithm computation count does not...
