说明：  国外模式识别课上老师给的pca和lle代码(These codes are given by the teacher in the pattern recognition class)

直接型到级联型的形式转换 ％ [b0,B,A]=dir2cas(b,a) ％b 为直接型的分子多项式系数 ％a 为直接型的分母多项式系数 ％b0为增益系数 ％B 为包含各bk的K乘3维实系数矩阵 ％A 为包含各ak的K乘3维实系数矩阵 ％(directly to the cascade-type conversion in the form of%% [belts, B, A] = dir2cas (b, a)% b-to direct the molecular polynomial coefficients% for a direct-denominator polynomial coefficients% of the gain coefficient belts% B To contain the bk K by the three-dimensional real coefficient matrix% A to include all ak K by the three-dimensional real coefficient matrix%)

this is coding of dwt in matlab

带中文注释的主成份分析 PCA源代码在matlab的实现 (Annotated with the Chinese to achieve pca algorithm matlab)

gabor是将图像转换成gabor特征，增强系统鲁棒性，使其不易受外界条件影响；norm是将图像的灰度值统一归一到一个范围内，便于同等使用图像。(gabor gabor is a feature to convert images to enhance the system robustness to make it less susceptible to external conditions affect norm is a uniform gray value image normalized 1-1 range, the same easy to use images.)

阻尼递推最小二乘法,用于系统辨识，效果良好(Damped least square method, used for system identification, the effect is good)
