说明：  这是一个能根据输入的符号表达式画三维或二维图形的matlab程序。(This is a symbolic import of expression 2D or 3D drawing of Matlab graphics procedures.)

Koch分形曲线计算地图边界，此程序能较好的计算任意凸图形边界长度。程序计算步骤为：提取图形边界，将边界点按与中心点所成角度排序，每隔一定角度取一边界点，对选取的边界点做3次迭代Koch分形(Koch fractal curve map boundary, this procedure can be better calculated arbitrary convex graphical boundary length. The program calculation steps: to extract graphical boundary, the boundary points and the center point of the angled Sort every angle to take a boundary point, done the 3 iterations Koch fractal selected border points)

these code implement convolutional coder and decoder used in LTE mobiles. this code used in 4G mobiles release 8.

说明：  数字语音信号处理中重叠相加法的matlab文件，用于编写帧合并的函数。(In digital speech signal processing, the matlab file of overlapping addition method is used to write the function of frame merging.)

数值分析—Gauss列主元消去法和龙格积分法(Numerical Analysis)

说明：  基于HMM的语音识别程序 很完整详细 里面包括10几个独立的小程序(HMM-based speech recognition procedures are complete details of which includes 10 small program that several independent)

实现并网，同频同相，实现内环电流的解耦控制，实现功率外环控制的单相并网逆变器(Achieve grid inner current decoupling control the same frequency and phase, the the power outer loop control single-phase grid-connected inverter)

Project System Identification submit

There is a code for spectrum sensing..in this code roc curve is generated..

这是信号处理中循环谱密度的一个DEMO，有些文章中称其为循环平稳信号的组合切片(A demo of cyclic spectra density. it also can be called combinated splice on cyclostationary signal in some papers.)
