比较五种窗函数特性matlab程序：得到矩形窗、海明窗、三角窗、汉宁窗和布莱克曼窗图形。从仿真结果可知：矩形窗设计的过渡带最窄，但阻带最小衰减也最差。布莱克曼窗设计的阻带最小衰减最好，但过渡带最宽。-Comparison of characteristics of five kinds of window function matlab program: to be a rectangular window, Hamming window, triangular window, Hanning window and Blackman window graphics. From the simulation results we can see: the rectangular window designed for narrow transition zone, but the minimum stop-band attenuation is also the worst. Blackman window design of the stop-band minimum attenuation is best, but the transitional zone widest.

（1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象；
（2）将所有子图象按列相接变成一个81维的行向量；
（3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量；
（4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。
（5）求出所有子块的特征向量。
