计算超声波入射到介质中，与缺陷作用时，其纵波衍射与横波衍射的衍射系数(When calculating the ultrasonic incident to the media, and defects, its longitudinal wave diffraction and the diffraction coefficient of the shear wave diffraction)

Given an output function f(x) and a cost function J(x) (and gradients), optimal inverse functions are found which produce the input x* with the lowest cost based on the current desired output. Output and cost functions produce a scalar. The method is demonstrated on 2D problems (for convenient visualization). With 2D plots removed (all but Figure 41), the code can run higher dimension systems also.

基于最小二乘法和最小均方误差法的信道估计，包括详细的仿真结果，如误码率和均方误差。(Based on the least squares and minimum mean square error of channel estimation methods, including detailed simulation results, such as error rate and MSE.)

牛顿拉夫逊算法进行潮流计算,希望能对大家的学习有所帮助，(Newton Raphson power flow calculation algorithm the hope that it can help everyone to learn,)

基于最小均方误差的最小二乘滤波器的设计算法(Based on the minimum mean square error of the least squares filter design algorithms)

The PID controller is the most widely used controller in industrial systems. However, appropriately tuning a PID controller is not an easy task although it has only three parameters at most. This submission provides a tool for beginners to learn PID tuning.

This is a file for alphabet recognition as for accident with matlab

This function is to obtain state of the art histogram based features like Mean, variance etc

On the companion website, you will find in the directory Chap exercises/chapter3 a workspace ex3M1.mat. Load this workspace and plot the speech waveform labeled speech1 10k. This speech segment was taken a vowel sound that is approximately periodic, 25 ms in duration, and sampled at 10000 samples/s.

说明：  自己做的SVPWM仿真，包括扇区检测等，很全(To do their own SVPWM simulation, including sector detection, it is all)
