此程序用于求有向网路和无向网路的节点的度(This procedure is used to beg for the degree of the nodes of the network to the Internet and no)

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. )

基于趋近律的滑模鲁棒控制 一个系统仿真实例(Reaching Law Sliding based robust control Simulation examples)

利用卡尔曼算法做出的平衡车整套程序，可以给做平衡车初学者很好的借鉴( Kalman algorithms make use of the balance of the car the entire procedure can be done to balance the car a good reference for beginners)

there is some code in matlab that will provide help in the field if digital image processing.it includes the code of extracting region of interst, median filter, nearest neighbour point sampling technique, negative of an image etc. and it is done by myself because i am doing becholar of computer science.it does not include any copyrighted content.i hope it will help thoes people that required help in the field of digital image processing.

四旋翼无人机SIMULINK建模，PSO_SA优化PID参数 reverse.m 作用：将History表中的string形式的key值转换为赋给九个全局变量temp00， ... ,temp08运行sum1.slx，可以直接观察此组参数的波形。 History 作用：映射表，将一组参数（temp00, ..., temp08）映射到这组参数的ITAE指标。 trojectory.m 作用：定义一条路径并进行路径压缩，通过不断向sum.slx传递位置参数，控制无人机运动，并接受无人机运动过程，做出无人机运动位置图像。 sum1.slx 作用：从外部接受一组位置关系（x,y,z）,模拟无人机由原点(0,0,0)运动到该位置并保持稳态这个过程中无人机的位置变化，并向外部反馈。 PSO_3D.m 作用：调用sum3D.slx，通过PSO得到内循环最优解的参数。 sum3D.slx 作用：获取.m文件中设置好的全局变量的值，模拟内循环三个角度的变化。 PSO_History.m 作用：调用sum9D.slx，通过PSO得到外循环最优解的参数，此过程已被History表优化。 PSO_SA.m 作用：调用sum9D.slx，通过PSO得到外循环最优解的参数，此文件在PSO_History.m基础上被模拟退火算法优化(Four rotor UAV SIMULINK modeling, PSO_SA optimize PID parameters)
