这是关于07年全国大学生数学建模B题，评委及出题者的评卷综述，具有很强的指导意义，很多参加了的同学，可以看一看是否领会了出题者的意图。(This is CUMUM B problem analysis.)

基于matlab的人脸识别算法pca，有应用matlab进行编程的源代码,以及运行需要的图象文件(Based on face recognition algorithm pca matlab application matlab programming source code, as well as needed for the operation of the image file)

这是一位博士写的一种新的正弦信号频率估计方法，很有参考意义。(This is a Ph.D. to write a new method of sinusoidal frequency estimation, lot of reference value.)

说明：  ecg preprocessing baseline removal, powerline interferance removing

it is a matlab code (simulink) that simulate two jack that they ascend a load with feedback.that load would not to being sloped.
