介绍C的好书,里面介绍了很多编程的知识，指的我们赌一赌，看一看(a book about c,it is a good description about c.and you can devalop your knowledge.)

power saving visual basic code1

this is matlab code for create admittance matrix

医学仪器课程做的CT成像原理——radon变换(medical equipment courses do CT imaging principle-- in Chinese Transform)

数字图像处理中的小波去噪代码！ 希望对大家有用 matlab(Digital image processing in the wavelet de-noising code! Want to be useful to everyone matlab)

matlab程序,用于matlab的学习及经验积累，相信会对你有帮助的(the programe of matlab)

卷积码的详细维特比译码,适合初学者 (For more than Witte convolution code decoding, suitable for beginners)

matlab数值计算，包括解方程，求极值，微分，统计，拟合和插值等函数。(matlab numerical calculation, including the solution of equations, and extreme, differential, statistics, such as function fitting and interpolation.)

对于无源定位系统，采用扩展卡尔曼滤波的方法对定位精度进行了分析。(For the passive positioning system, using the extended Calman filter method for positioning precision was analyzed.)

本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)
