说明：  _余松煜数字图像处理，非常好的一本书~非常有用(_ Song-Yu Yu digital image processing, a very good book ~ very useful)

这是一个有关中国邮递员的问题的算法，可以用于许多实际的问题(This is an issue of the Chinese postman algorithm can be used for many practical problems)

mann-kendall test in time seri

说明：  用matlab读取uff格式的数据文件。(load the data type of *.uff using matlab.)

遗传算法实现最优化问题的解，适合初学者使用，稍加改进即可实现tsp问题的求解(Genetic algorithm optimization solution, suitable for beginners, a little to improve the problem can be solved to achieve tsp)

三相逆变桥PWM电流滞环控制Simulink仿真，另加一滤波器观看PWM经过低通滤波后的波形，适合电力电子初学者(Three-phase PWM inverter current hysteresis control Simulink simulation, plus a watch PWM filter through after the low-pass wave filter for power electronics for beginners)

the HF principle for calculating diffraction pattern from pinhole.

说明：  粒子滤波算法与扩展卡尔曼滤波算法的比较方法。(Particle filter and extended Kalman filter algorithm for comparison.)

Economic dispatch by using PSO method

置信传播是一中很有效的算法，将其应用于检测，通过在检测与译码之间迭代交换传递信息，并有选择地通过单边消息传递来更新信息，降低系统实现的复杂度。 (Belief propagation is a very efficient algorithm to be applied to the detection, the information transmitted by the exchange between the iterative detection and decoding, and to update the information, to reduce the complexity of system implementation is selectively transmitted through unilateral messages.)
