It turns out that information that would be significant for x1 in the first
equation is lost in the truncated arithmetic that says that 1+1/\4 ε=1/\4.There
is a fix for problems such as this,namely a technique called partial pivoting.
The idea is fairly simple:Do not choose the next available column entry for
a pivot.Rather,search down the column in question for the largest entry (in Pivoting
Strategies absolute value).

原来的信息,将显fi斜面X1在firstequation迷失在截断算法,称1 + 1 / \4ε= 1 \ / \4.有一个fiX对这样的问题,即一种称为部分旋转.这个想法是相当简单的：不要选择下一个可用列输入一枢轴.相反,搜索下列问题最大的入口（在pivotingstrategies绝对值）太厉害了最后问一个Then switch rows, if necessary, and use this entry as a pivot.然后切换行，如果有必要的话，使用此项为支点
