一种多尺度方向场修正的指纹图像处理新方法，对于低质指纹图像，能够很好的求取其方向场。(source code for fingerprint orientation calculation)

本文详细的介绍了FM信号产生和接收的方法，并给出了详细的matlab程序(producing and receiving FM signals)

CHAPTER 10 控制系統的設計 許多受控程序的轉移函數包含一對或更多對的共軛複數極點。在s 平面中若複數 根非常接近虛數軸，則閉迴路系統會變成輕微阻尼或不穩定(CHAPTER 10 control system design of many controlled program transfer function contains a pair or more pairs of conjugate complex number of poles. If the plural in the s-plane root number very close to the imaginary axis, then the closed loop system becomes slightly damped or unstable)

系统的学习预测控制，尤其是动态矩阵控制有关的系统分析，算法，改进和应用。(The learning predictive control of the system, especially the system analysis, algorithm, improvement and application of dynamic matrix control.)

说明：  实现了lfm信号的仿真，可以对其频谱和时域波形进行分析，并且仿真了其模糊函数，可以分析其雷达性能。(The simulation of LFM signal is realized, and its spectrum and time domain waveform can be analyzed, and its ambiguity function can be simulated to analyze its radar performance.)

线性调频脉冲压缩的Matlab程序,实现了对10个数字音的识别程序使用高阶累积量对MPSK信号进行调制识别，music高阶谱分析算法，能量谱分析计算,鲁棒性好，性能优越。

mtlab的遗传算法的源程序,很好用的,这是个压缩文件,请解压缩后使用(mtlab genetic algorithm source, the good, it is a compressed file, decompress after use)
