Secondly, the method applies a linear iterative procedure in calculation and the SVD is used as a main tool, avoiding complex nonlinear optimization processes. 實(shí)現過(guò)程是以奇異值分解為基本工具的分步線(xiàn)性迭代計算，避免了傳統射影重建方法復雜的非線(xiàn)性?xún)?yōu)化環(huán)節。
At the same time, through the contrasting calculation of an engineering optimization problem, the astringency and engineering usability of this modifier algorithm are proved. 通過(guò)一個(gè)工程優(yōu)化問(wèn)題的對比計算，驗證了這種迭代計算方法的收斂性以及工程適用性。
