matlab实现的线性调频信号的小波变换，可实现信号的时频分析

AMplitude, Frecuency and Phase Modulation with Matlab

模型是结构体类型的线性投影Y = linproj(X, model) 其中W.model为线性投影矩阵， Y = model.W *X + model.b b为偏差值( Description: Y = linproj(X, model) linearly projects data in X such that Y = model.W *X+ model.b out_data = linproj(in_data, model) projects in_data.X out_data.X = model.W *in_data.X+ model.b out_data.y = in_data.y Input: model [struct] linear projection: .W [dim x ncomp] Projection matrix. .b [ncomp x 1] Bias.)

先做灰階圖片，再利用IMHIST來做統計，在做SMOOTH來讓使用者更容易了解圖片的特色 (Grayscale images do first, and then use IMHIST do statistics, SMOOTH do to make it easier for users to understand the characteristics of the picture)

一种ESPRIT算法（教学实验，对初学者很有帮助）(a kind of ESPRIT , it may be helpful to the leaner of matlab and signal processing)

这个是编的BP神经网络的程序，对于初学神经网络的人有很好的借鉴(This is a series of BP neural network program, for the beginner neural network is a good reference)

做DEA用的,功能很强大,大家可以试试看,真的很好用(DEA do use, very powerful, we can try, really well)

说明：  人脸识别程序，主要运用了harr-like算法，在matlab下运行(Face recognition program, the main use of the harr-like algorithm to run in matlab)

模糊聚类分析，MATLAB编程实现，很好的很经典的源代码，有详细解释(Fuzzy clustering analysis, MATLAB programming, good classic source code, a detailed explanation)

使用Matlab进行wav文件的基音频率提取，包括自相关法、平均幅度差法和倒谱法等。(Wav files in Matlab to extract the pitch frequency, including the auto-correlation method, average magnitude difference method and the cepstrum method.)

说明：  傅里叶变换的全相位分析，适合初学者参考，用时将后缀改成.7z(Full phase analysis of Fourier transform, suitable for beginners)
