matlab code for heart demo

一个写的比较好的人工鱼群算法,适合初学者.(A good written artificial fish school algorithm, suitable for beginners.)

该程序为岭回归在决策分析中的应用，能够给出最优的各组分的回归系数(The program for the ridge regression in the application of decision analysis, be able to give the best of each component regression coefficients)

matlab的simulink仿真，一个关于通信系统的仿真设计，文件太大，这是第七部分-simulink of matlab simulation, a simulation on the communication system design, file is too large, this is part VII

simulation in matlab simulink of a pv array for solar energy conversion

LDPC码的matlab实现，把解码的部分改过了，实验过很多次，符合理论要求，码长越长误码率越低(The implementation of LDPC code in MATLAB has changed the decoding part. It has been experimented many times and meets the theoretical requirements. The longer the code length, the lower the bit error rate.)

象的分割与检测(识别)实际上是一项非常困难的工作。很难说清楚为什么图象应该分割成这样而不是那样。人类的视觉系统是非常优越的，它不仅包含了双眼，还包括了大脑，可以从很复杂的景物中分开并识别每个物体，甚至可以毫不费力地跟上每秒好几十帧变化的图象。

将彩色图转化成灰度图，在此基础上统计连通区域，根据一定的统计特性，设置一定的准则，检测出人脸。

一个50行的简短Matlab有限元程序，求解三维线弹性问题。执行fem3d.m即可。(A brief 50-line Matlab finite element program for solving three-dimensional linear elastic problem. Executive fem3d.m .)

说明：  用matlab平台实现的拉格朗日插值算法（另附一个插值算法）(Matlab platform with the Lagrange interpolation algorithm (followed by an interpolation algorithm))
