The length of the diagonal side will be the square root of 2. This diagonal will be used to construct the next square root by employing a similar method.
对角线的长度是2的平方根。应用类似的方法，这个对角线会被用来构造下一个平方根。
It is shown that, if algorithms for performing the QR decomposition are free from calculation of square root, the related iterative refinement algorithms can also be square root free.
证明了：若用QR分解所作的算法无需计算平方根，则相应的迭代加细算法也无需计算平方根。
Coefficient determination, absolute bias, relative absolute bias, root mean square error and relative root mean square error were employed to evaluate the precision of different model systems.
