经典的hough直线变换检测算法，可以极坐标进行转换，然后再检测直线(Line detection algorithm)

九点差分格式，精度比五点差分要高，对于实现有限差分，是一个重要的程序(Nine-point difference scheme, the accuracy than the five-point difference is higher, for the realization of finite-difference, is an important procedure)

这个函数返回n点2dw波段的傅里叶变换的DFT样本序列。通常情况下，以插值点的方式进行放大。(This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.)

a good book and mifie in pde

basic calculator using matlab...with GUI

本文件用于KMV模型的计算，包括资产价值、资产波动率、违约距离、违约概率等计算(This document is used for the calculation of KMV model, including asset value, asset volatility, default distance, default probability and so on)

建立包含直驱型风力发电机、单级式光伏发电系统和储能蓄电池的风能与光伏混合微电网模型。混合微电网在并网运行时，通过储能蓄电池平滑风能和光伏电源的输出功率波动，维持公共连接点电压。A wind power and photovoltaic hybrid microgrid model including direct drive wind turbine, single-stage photovoltaic power generation system and energy storage battery is established. When the hybrid microgrid is connected to the grid, it can maintain the voltage of the common connection point by fluctuating the output power of the energy storage battery smoothing wind energy and the photovoltaic power.(A wind power and photovoltaic hybrid microgrid model including direct drive wind turbine, single-stage photovoltaic power generation system and energy storage battery is established.
