BFGS

说明：  谐波源案例，基于matlab/simulink的谐波源案例。(Harmonic source case)

自助法（Bootstrap）的matlab源码，在小样本统计学中很有用(matlab code for Bootstrap method)

能够用DFT方法求信号的相量,非常的精确，实时性能得到保证(It can solve the problem of sigal s phasor based on DFT)

加权中值滤波，用于图像增强，只用于超声图像，对超声图像去噪有很好的效果。内还包括信噪比计算方法。(weighted median filter for image enhancement, only for ultrasound images of ultrasound image denoising with very good results. Which is also a signal-to-noise ratio calculation.)

Calculation the impedance of Passive Power Filter
