Ashrea模型 太阳瞬时辐射强度预测 任何地点 任何时间(Ashrea instantaneous solar radiation intensity prediction model anywhere at any time)

说明：  一段波束形成的小程序，用matlab实现(Beamforming for some small procedures, using matlab to achieve)

MATKAB实现CDMA System 仿真(Coaxial Cable Based CDMA System Simulation)

In this program, a 20 micron x 8 micron platform is taken with closely placed slits emitting light at the upper border of domain which extend only in the third dimension perpendicular to the plane of simulation and which are projected as just point sources in the simulation domain. The region surrounding the waveguide are filled with air of refractive index, n=1.

C4.5的matlab实现，并且进行了详细的注释，并进行了有序化处理(C4.5 matlab realize, and conducted a detailed notes, and conducted an orderly processing)

Audio signal modelling containing a sequence of 2 identical chirp signals with an addition to filtering an image using simple low-pass 1-D filter.

k-means 源代码 k-means is a very useful hierarchical clustering in meachine learning (k-means is a very useful hierarchical clustering in meachine learning )

利用matlab的图像滤波说明，有源代码，很管用的(Note the use of matlab for image filtering, active code, it is useful to)

该书籍详细介绍了matlab仿真的具体实现方法，对初学者掌握仿真技能十分有利。(The book details the specific method matlab simulation, simulation for beginners to master the skills are very favorable.)
