模式识别经典书籍，模式识别工具书必备之一(Pattern Classification CH)

Find indexes neighbors

说明：  基于细菌觅食算法的MPPT算法，可以用来做课设，方便实用！(MPPT algorithm based on bacterial foraging algorithm)

It covers the basics matlab code for opamp design. Vishal Saxena designed this kit for Op amp and this will effectively reduce the learning curve involved with matlab code.

Lempel ziv algorithm compression

说明：  基于Matlab编写的用于对数据进行插值分析和傅立叶变换的程序(Based on Matlab for the preparation of the data analysis and Fourier transform interpolation procedures)

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

说明：  常用的matlab代码文件，可以借鉴一下，有一定意义(Commonly used matlab code file, you can learn what it has a certain sense)

把三角函数的和 按周期的不同 把需要的周期函数 抽出来 相当于滤波器的作用(The trigonometric functions and the need to press the different cycles of periodic functions to extract the equivalent filter function)

斑纹噪声消除，matlab代码，里面有测试图像和我自己写的dicom文件处理参数(Speckle noise reduction, matlab code, there are test images and I wrote it myself DICOM document processing parameters)
