Several important matrix function such as e〓, log (1+A), cos (1+A) and A〓 are approximated via truncated matrix continued fractions, and the error bounds associated with the continued fraction approximants of these matrix function are given.

在第六章，我们研究了矩阵函数的数值计算，我们给出了几个比较重要的矩阵函数如e〓，log（1+A），cos与A〓的连分式逼近算法，并给出了各自的误差分析。

Normal distribution in statistics is based on the probability density function in the form of representation, and set up a continuous random variable X, the probability density function f has the form of Figure 1, where a, b are constants and were known as the average value and standard deviation,π, e, respectively pi and natural constants, claimed that X subject to parameters a, b of the normal distribution.

正态分布在统计学中是以概率密度函数的形式表述的，设连续型随机变量X的概率密度函数f有图1中的形式，其中a、b为常数，分别被称为平均值和标准差，π、e 分别为圆周率和自然常数，则称X服从参数为a，b的正态分布。

If each term of the series u1+u2+…un+…is continuous on the interval［a,b］, and this series is uniformly convergent on［a,b］, then its sum function is also continuous on ［a,b］.

若级数u1+u2+…un+…的每一项在［a，b］上连续，而且这级数在［a，b］上一致收敛，则它的和函数也在［a，b］上连续

Up to a certain cube, we put the A items — the best sellers — in a six-level pick tower, explains Rita Hoffman, vice president, operations with Murray Feiss. Conveyable larger best sellers — the B items — also are in a convenient pick area. Less frequent selling C items are in a less accessible area.

Murray Feiss 公司的运作副总经理Rita Hoffman 先生说："我们将A类产品——最畅销的、达到一定体积的产品，放在六层的分拣塔上；" B类产品——很畅销的、易搬动的产品，则放在一个方便挑拣的区域；而C类产品——非畅销品，则被放在一个很少踏足的区域。
