利用matlab对信号做FFT变换，提取频率幅值，并以图形方式显示(Using matlab to do FFT transform the signal to extract the frequency amplitude, and graphically display)

自己写的matlab程序，用kay方法进行频率估计，已通过验证。(kay matlab)

for trainng the data.....

费舍尔判别法的人脸识别应用程序例子，希望有所帮助(Fisher Discriminant Method for Face Recognition application example for the help)

说明：  主要指令：butter（产生巴特沃斯滤波器）；freqz（绘制幅频、相频曲线）；zplane（绘制零、极点图）；ss2zp（状态方程变零、极点）；zp2tf（零、极点变分式多项式）。(Main instruction: butter (produced bart wo filter) Freqz (draw amplitude frequency, phase frequency curve) Zplane (draw zero, poles chart) Ss2zp (state equation is zero, poles) Zp2tf (zero, pole change fraction polynomial). )

matlab的学习教程，对于新上手的人来说，不错(matlab tutorials for new people to get started, good)

IEEE致力于电气、电子、计算机工程和与科学有关的领域的开发和研究，该程序为IEEE30节点潮流计算,电压初值计算，(IEEE is committed to electrical, electronics, computer engineering and science-related fields of development and research, the program flow calculation for the IEEE30 bus voltage initial calculations,)

特征点提取，一个关于harris算子提取图像特征的程序。。 做了些许改动(Feature point extracting，Harris operator on image feature extraction process. . Make a few changes )

该程序是MATLAB环境下的小波消噪程序，自我感觉很有用，在此分享(The program is under the MATLAB environment, wavelet denoising process, feel useful, to share in this)
