The condition number, defined below, is changed by scaling the matrix.

This paper introduces the accumulating method into the parameter estimation of GM(2,1) model and gets the new parameter estimation formula whose calculation is more simple than before. Meanwhile, the condition number of the new formula is mostly well-conditioned.

Zonal wavefront reconstructing model is adopted, the least squares solution is applied, and the condition number of wavefront reconstruction matrix is used to estimate how its morbidity is.

The regular numerical algorithm is MOM, whose general impedance matrix has a large condition number at the resonance frequency points, which brings an inaccurate result.
