说明：  CZT和FFT的C语言实现代码，能有效滤除谐波，噪声。获得信号的频率，是一种良好的频率测量算法。(CZT and FFT of the C language code, can effectively filter out harmonics and noise. Access to the signal frequency, is a good algorithm for frequency measurement.)

基于最小二乘估计的圆心拟合，可计算出圆心坐标及半径(Estimates based on least squares fitting of the center of a circle, calculate the center coordinates and radius)

实现互相关运算 C实现，实现互相关运算 C实现(cross correlation C code implementation)

读入断面数据，根据地形，水位,进行相应计算 (calculate the area and depth )

利用贝叶斯分类原理实现多义词的消歧。首先利用训练语料进行训练，然后基于机器已经获取的知识的基础上对生语料进行词义标注。(Realize the principle of the use of Bayesian classification polysemous word sense disambiguation. First of all, the use of training corpus for training, and then the machine has been based on knowledge gained on the basis of corpus for semantic tagging of Health.)

说明：  这个程序是关于轴承刚度方程的MATLAB程序(This program is about the bearing stiffness equation MATLAB program)

C++的求阶乘的程序，对本科C++课程可能有些帮助(Factorial in C++ program, it maybe helpful for some C++ course)

基于最小二乘法的抛物面拟合，内含有模拟数据和真是数据供参考。(Contains analog data based on the method of least squares parabolic fitting, and is really data for reference.)

计算离散傅里叶变换的一种快速算法，简称FFT。快速傅里叶变换是1965年由J.W.库利和T.W.图基提出的。采用这种算法能使计算机计算离散傅里叶变换所需要的乘法次数大为减少，特别是被变换的抽样点数N越多，FFT算法计算量的节省就越显著。(A computing discrete Fourier transform fast algorithm, referred to as FFT. Fast Fourier Transform in 1965 by the JW Cooley and TW Tuji Ti out. Using this algorithm enables a computer to calculate the number of multiplications needed for the discrete Fourier transform greatly reduced, especially sampling points N is transformed more and save FFT algorithm to calculate the amount of the more remarkable.)

利用emd算法解决经验模式分解的一些存在的端点效应问题。 有效的解决了问题。(Using emd algorithm to solve some of the empirical mode decomposition end effects exist. Effective solution to the problem.)
