The least square conjugate gradient and odd values decomposition method also can be used to perform tomographic inversion. 研制的最小平方共轭梯度算法和奇异值分解法也可进行同样的层析反演。
Also, three filter factors in the phasor deconvolution algorithm have been designed by using the least Square technique based on the geometrical factor theory. 基于几何因子理论用最小平方滤波法设计出了相量反褶积中的三个滤波因子。
