分前后两级，前级boost升压电路，后级三相全桥逆变(Points before and after the two pre-boost boost circuit, after three-phase full-bridge inverter)

MATLAB 阻抗计算例子5，很有参考价值。。(MATLAB impedance calculation example 1, a good reference. .)

This code applies local histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The window size may be changed, however, the window shift is as per size of the window. The output is definitely a better contrast image as compared to the input but checkerboard effect is evident.

通用的牛顿拉夫逊法潮流计算程序，可以自行输入支路参数矩阵，节点参数矩阵。(Universal Newton Raphson power flow )

基于Mesri蠕变模型的桥梁桩基工后沉降计算程序(Calculation program for post-construction settlement of bridge pile foundation based on Mesri creep model)

itk是美国国家卫生部开发的图像处理程序，但是使用不便，所以制作了他的matlab接口(itk is the United States National Institutes of Health to develop image processing procedures, but the use of inconvenience, so the production of his matlab interface)

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 ( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal OFDM symbol Nfft = 128 points a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64 )
