Examples
- Astro - geodetic network
天文大地网 - It is demonstrated that the solution for 141 000 order normal equations for a simulated astro - geodetic network ( 47 057 points ) and a space one ( 476 points ) iterates 4 993 times to converge to 1 10 - 18 second , taking 28 min and 47 seconds , on a pii / 233 computer , showing over 40 times more efficiency , as compared with the coefficients unadjusted
利用模拟的天文大地网( 47057点)和空间网( 476点)在pii / 233微机上解算14 . 1万阶方程组共迭代4993次(收敛至1 10 - 18角秒) ，花费机时28分47秒，与未进行系数调整相比，功效提高40多倍。
