很好的matlab英文教程，不错的奥，值得看。(matlab)

说明：  采用最新的人工智能算法，对城市问题（tsp）问题进行了很好的解决(Using the latest artificial intelligence algorithms, to urban problems (tsp) had a very good problem to solve)

基于光正交码构造了一类新的不规则00c—LDPc码．新的LDPC码是准循环码，其编码复杂度与码长成 线性关系，具有编码复杂度低的特点，它所对应的双向图中没有四线循环．用和积译码算法对新的码字进行了仿 真，结果表明，与具有类似参数的随机码和规则OOc—LDPc码相比，当信道误码率为10。5时，译码增益分别为 0．3和0．15 dB．(Construct a new class of irregular the 00c-LDPc code based on optical orthogonal codes. LDPC codes are quasi-cyclic code, its complex coding with code length linear relationship, with low encoding complexity, the corresponding bidirectional Figure it in four-wire loop. Simulation with integrated decoding algorithm of the new code word, the results show that when the channel bit error rate, compared with the random codes with similar parameters and rules OOc-LDPc code decoding gain were 10.5 0.3 and 0.15 dB.)

MATLAB编写的，基于Newmark-beta法的求解微分方程的解法。(method to solve the differential equation,based on the Newmark-beta method.)

说明：  本代码为天线的发射分集代码，已经在MATLAB环境下调试过。(The code for the antenna transmit diversity codes, have been tried in the MATLAB environment down.)

说明：  画出函数的ROC曲线，precision/recall 曲线(function [prec, tpr, fpr, thresh] = prec_rec(score, target, varargin) PREC_REC- Compute and plot precision/recall and ROC curves.)

非常好用和实用的直线拟合MATLAB小程序。(Very easy to use and practical linear fitting MATLAB applet.)
