说明：  使用libsvm进行三分类，svm多分类可以类似编程(Use libsvm for three categories, svm classification can be more similar to programming)

提供了4-psk的matlab源程序包，包括主函数和子函数，可供初学者学习参考。(Provides a 4-psk the matlab source code package, including the main function and Functions for beginners to learn the reference.)

说明：  涡流计算的流场程序，适合于流场初级者的研究(Vortex flow calculation procedure is suitable for those who study the primary flow field)

傅 立叶变换是数字信号处理领域一种很重要的算法。要知道傅立叶变换算法的 意义，首先要了解傅立叶原理的意义。傅立叶原理表明：任何连续测量的时序或 信号，都 可以表示为不同频率的正弦波信号的无限叠加。而根据该原理创立的 傅立叶变换算法利用直接测量到的原始信号，以累加方式来计算该信号中不同正 弦波信号的频 率、振幅和相位。 (The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used. Together with a great variety, the subject also has a great coherence, and the hope is students come to appreciate both. )

MATLAB30个案例配套的例子，便于学习。(Examples of MATLAB30 cases are easy to learn.)

说明了MATPOWER 4.0b3版本的具体操作细节(Matpower 4.0b3 User s Manual)

粒子群算法（PSO）整定pid控制参数，比传统Z-N整定方法要好，内附matlab程序与simulink模型(Particle swarm optimization (PSO) is better than traditional Z-N tuning method in tuning PID control parameters. It includes matlab program and Simulink model.)

this is a curvelet transform

3. Setting of a suitable threshold value.Then apply wavelet de-noising and compression on wavelet coefficients and thresohlding using global positive threshold value. So that a compressed image can be transmitted in an efficient manner.
