1. 统计工资 设计要求： （1） 使用结构数组设计一个公司职员的数据结构，使用下述的结构定义： struct employee{ int age char name[15] double salary } （2） 在主函数里构造一个数组company，用来存放职工信息。 （3） 设计update函数，用来对company中指定职员的信息进行更改。要求先按照name查询到相应的职员，然后修改并保存。 （4） 设计一个read函数，用来向company中录入职员信息，并显示结果。 （5） 编写mean函数求平均工资。 应该能对全体职工或大于某一年龄的职工工资求和并计算平均值。 （6） 编写total函数对工资求和。 应该能对全体职工或某一年龄段职工的工资求和。

This paper studies the problem of tracking a ballistic object in the reentry phase by processing radar measurements. A suitable (highly nonlinear) model of target motion is developed and the theoretical Cramer—Rao lower bounds (CRLB) of estimation error are derived. The estimation performance (error mean and

It can be argued that the current free-software movement is the most important thing happening in computing today. We are in the midst of a major shift from all software being proprietary and closely held by individual companies to a large body of software that can be freely acquired and used by anyone for any purpose. Free software now includes not only programming language compilers and linkers, but numerous utilities, graphical user interface environments, and even entire operating systems.

cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide. the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972. here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation. you can select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont count). to eliminate these too, would involve ieee hackery.

在Windows的资源管理器中选择文件时是不是觉得有一些麻烦，我们在DOS下使用拷贝命令时使用通配符可是非常方便的呀！而在资源管理器中选择多个文件时，我们必须使用鼠标配合Shift、Ctrl键来操作，非常麻烦，弄不好还得重来。

The Kalman filter is a set of mathematical equations that provides an efficient computational [recursive] means to estimate the state of a process, in a way that minimizes the mean of the squared error. The filter is very powerful in several aspects: it supports estimations of past, present, and even future states, and it can do so even when the precise nature of the modeled system is unknown.

The double-density DWT is an improvement upon the critically sampled DWT with important additional properties: (1) It employs one scaling function and two distinct wavelets, which are designed to be offset from one another by one half, (2) The double-density DWT is overcomplete by a factor of two, and (3) It is nearly shift-invariant. In two dimensions, this transform outperforms the standard DWT in terms of denoising however, there is room for improvement because not all of the wavelets are directional. That is, although the double-density DWT utilizes more wavelets, some lack a dominant spatial orientation, which prevents them from being able to isolate those directions.
