逆变器仿真程序,模拟AC-DC，需要者可以参考(Inverter simulation, simulation of AC- DC, those can be reference )

For all classifier needs feature classification object .Here the program for height and width feature taken hand image.This program suitable for any single object in the image. input gray_img : input hand image or any measure image like 2d with 0 to 255 intensity output height : pixel count of height width : pixel count of width out_img : segmented image with line for height and width hand_height_width function implements hand height and width of the image using the method outlined in: calculate the hand height and width value for gray image. In Proceedings of the Information Sciences 275 (2014) 45–56. Hand shape identification on multirange images. [ height width out_img ] = hand_height_width ( gray_img ) function is to find the hand height and width value of the image. The input is given to the gray scale image.

基于差分进化算法的无线传感器网络节点定位方法研究(Based on differential evolution algorithm for wireless sensor network node localization method)

说明：  采用谱元法计算声传播问题，带matlab代码(spectral method used for wave transmission problems, with matlab code)

找到贝塞尔函数J(n,x)=0或 Y(n,x）=0的前k个解(Find first k positive zeros of the Bessel function J(n,x) or Y(n,x) using Halley s method.)

基于CP的最大似然估计仿真图，两幅图，分别是符号定时偏差，以及频偏，从图中可以看出在符号定时估计最大处，相应的频偏估计值也是最接近的(CP-based maximum likelihood estimate simulation map, two maps, are a symbol timing offset, and frequency offset, it can be seen the figure in the symbol timing estimation is maximum, the corresponding value is also the closest frequency estimation)
