MATLAB DATAMINING COURSE CODE

This code is about SVD method in seismic.

说明：  VC与matlab的混合编写程序的COM方法，如何调用COM进行混合编程。(Mixture of VC and matlab programming of COM methods, how to call COM mixed programming.)

利用matlab，计算三角晶格光子晶体能带图(Using matlab,we calculated triangular lattice photonic crystal energy band diagram)

小波变换及编码在图像图形处理中有着重要的应用，本压缩包属于小波编码及其演示的matlab库函数，希望对大家的学习有帮助。(Wavelet transform and image coding has important applications in graphics processing, the wavelet encoding and compression packages are demo matlab library function, we hope to help learning.)

平面近场声全息点源仿真程序，由全息面反推重建面声压信息(NAH )

各种随机信号的自相关函数和功率谱密度函数、画图(Autocorrelation function and power spectral density function of a variety of random signals, drawing)

说明：  认知无线电技术的提出是为提高频谱利用率，而认知无线实现的关键技术是频谱感知，众所周知协作检测提高了衰落环境中认知用户系统检测的性能，该文章是基于协作检测提出新的检测方案，利用了双门限方法提高了系统性能，兼顾带宽有限和增强性能两个方面，是基于门限检测的协作检测性能优化的前提。对以后门限优化协作检测非常有用。(In this paper, we employ a double threshold method in energy detector to perform spectrum sensing, while a fusion center in the cognitive radio network collects the local decisions and observational values of the secondary users, and then makes the final decision to determine whether the primary user is absence or not. Simulation results will show that the spectrum sensing performance channels is improved significantly under the proposed scheme as opposed to the conventional method.)

说明：  这是关于非线性单摆的混沌解法后期出现的庞加莱图的matlab程序 (This is a nonlinear pendulum on the latter part of the chaotic solution of the Poincare map matlab program)

说明：  为了采集准确的心电信号，设计了一套基于瞬时心率信号抗干扰测量的方法，针对微弱并易受干扰的心电采样信号，进行有效地硬件以及软件滤波，通过软件数字滤波算法，得到真实的心率信号(Set based on the instantaneous heart rate signal immunity measuring method to collect accurate ECG, ECG sampling signal for the weak and vulnerable to interference, hardware and software filtering, digital filtering algorithm through software, get real The heart rate signal)
