this is the source code for the radon transform. it is the c file. u have to save this file as c file and then compile it using mex compiler in matlab.

this code about optimization

经过调试的svm分类程序，很好用，对初学者很有帮助。(After commissioning of the svm classification procedures, useful, useful for beginners.)

FM demodulation signal

粒子群算法，用于对物流供应进行最优化的一种数学模型，本例中是设计了十个销售点的模型(Particle swarm algorithm for optimizing the logistics supply a mathematical model, in this case is the design of the 10 model point of sale)

说明：  加速度计的BS2源程序 简单易学 由parallax公司提供(The BS2 source programme of accelerator)

说明：  约瑟夫问题的实现：设有n个人围坐在圆桌周围，现从某个位置m（1≤m≤n）上的人开始报数，报数到k的人就站出来。下一个人，即原来的第k+1个位置上的人，又从1开始报数，再报数到k的人站出来。依此重复下去，直到全部的人都站出来为止。试设计一个程序求出出列序列。(Joseph realized the problem: There are n people sitting around the round table, is from a position of m (1 ≤ m ≤ n) reported on the number of people began to be reported to the k number of people to come forward. The next person, that is, the original positions on the first k+1 people, and from the number reported at 1, then the number reported to the k to stand up. So repeat this until all the others can stand up. Try to design a program derived from the column sequence.)

基于matlab的QPSK实现，包含高斯信道和理想信道的调制、解调、星座图、功率谱以及误码率，有详细注释，很值得参考，绝对可以用(Based on matlab QPSK implementation, including gaussian channel and ideal channel modulation and demodulation, constellation diagram, power spectrum and the bit error rate, has detailed notes, is worth reference, can be used absolutely )

this file is inoder to let you be able to use the aer block found n the matlba for matlab issues n order to stay in the situation while occuring

本例很好的解释了FFT变换的功能，例程简单易懂，能够很好的用于理解FFT，观察信号频谱。(In this case a good explanation of the function of FFT transform routines easy to understand, can be very good for understanding the FFT, observe the signal spectrum.)
