A Matlab IFFT implementation using matlab itself

guitar tuner for matlab

说明：  包含很多matlab实用程序，设计各个方面的应用。(Matlab contains a lot of utility, design all aspects of the application.)

基于双低频小波变换和k近邻分类器的人脸识别算法源程序(Dual low frequency wavelet transform and k-nearest neighbor classifier based face recognition algorithm source)

说明：  根据随机给出的二进制信号进行统2ASK调制,画出各个阶段的波形.(According to random binary signals given 2ASK modulation system, draw the various stages of waveform.)

irisData is 150x5. row: Sepal.Length Sepal.Width Petal.Length Petal.Width Group(1,2,or 3) the first 50x5 is Isis-setosa(1), the second 50x5 is Isis-versicolor(2), the last 50x5 is Isis-virginica(3). !!! Caution !!! X(50 + 21, :) equals X(50 + 50 + 27, :), but Y(50 + 50 + 21) DOESNOT equal Y(50 + 50 + 27)! So the algorithm will NEVER be 100 correct.

mit的信号处理考试试卷，非常棒！可以理解老美的学习思路。(mit signal processing exam papers, great! Americans can understand the idea of learning.)

两个很实用的ECG信号生成器，代码较长的那个能生成较为真实的健康个体的心电信号(Two very useful ECG signal generator, the code can generate more longer true that the health of the individual ECG)

利用自适应陷波器对引入单频干扰的原始正弦信号进行恢复(The use of adaptive notch filter for the introduction of single-frequency interference for the restoration of the original sinusoidal signal)

指纹识别的matlab程序，里面包括了一些指纹图片，利用gabor小波进行识别(Fingerprint recognition matlab program, which includes a number of fingerprint images using gabor wavelets to identify)
