实际模型 meaning in English
realistic model
Examples
- Abstract : a new preconditioner is proposed in the preconditioned conjugate gradient method ( pcg ) for solving the problem arising from image restoration . the condition number of the new preconditioned system is proved to be much less than the original one . numerical results show that the new method is better than the classical pcg
文摘:在图像恢复实际模型的预条件共轭梯度法中，提出了一种新的预处理算子.将新的预处理算子应用于原来的系统，证明了其条件数得到大大的改善.实验结果表明，新的预处理算子具有很大优越性，比传统的预处理算子具有更快的收敛速度
