主成分分析算法（PCA），这是一个外国人编写的，很具有参考价值(principal component analysis algorithm (PCA), which was prepared by a foreigner, it is very valuable reference)

这是一本关于数值计算方法的书，编程工具可选用matlab和mathematica(This is a book on numerical methods, programming tools can be used matlab and mathematica)

说明：  这是一个计算图像中的欧拉数的程序.先将图像二值化,然后再求反计算欧拉数(This is a calculated image of the Euler number of procedures. First two binary images, and then calculated for anti-Euler number)

Performance of QPSK and DQPSK in AWGN and Rayleigh Fading Channel. A detailed Report of the work done in the source code is also attached as another file

openMP merge sort code.

ADM算法，用于基于TV模型的压缩感知图片重构的快速算法，张印所编( ADM algorithm for picture compessing)

基于matlab的有限元法求解泊松方程，WORD的形式，里面附有源程序(Matlab-based finite element method for solving Poisson s equation)

这是两个关于插值和拟合的5个程序，可以适用些不能直接套用公式的情况，可能对部分人有用。(These are two of the interpolation and fitting of the five program, you can not directly apply the formula for some circumstances, may be useful for some people.)

说明：  一种改进的时钟定时抖动估计方法An improved estimation of clock timing jitter(An improved estimation of clock timing jitter)

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)
