iterative computations的用法和樣例：
例句
- The optimal solution can be approached by several times of iterative computation.
經若干次迭代計算，逐步逼近原問題的最優點。 - Secondly, the method applies a linear iterative procedure in calculation and the SVD is used as a main tool, avoiding complex nonlinear optimization processes.
實現過程是以奇異值分解為基本工具的分步線性迭代計算，避免了傳統射影重建方法複雜的非線性優化環節。
