EMC166

说明：  本书用c语言编写了科研和工程中最常用的166个算法,这些算法包括复数 运算、... 4.3.1 【算法23】求一般复矩阵的逆 4.3.2 【算法24】求对称正定矩阵的(good study)

分别对beta估计值模拟分析、非中心对称分布、卡方拟合优度检验、筛选抽样随机数抽取、有限样本性质模拟这5个内容进行了编程说明(The five contents of beta estimation simulation analysis, non-centrosymmetric distribution, chi-square goodness-of-fit test, random number extraction of screening sampling and Simulation of finite sample properties are explained by programming.)

说明：  二分法求方程数值解，程序含说明性文字，精度可调(The numerical solution of the equation is obtained by dichotomy. The program contains explanatory text and the precision is adjustable)

分数阶fourier变换程序，基于插值和抽取操作和卷积运算的快速算法。(Fractional fourier transform procedures, based on interpolation and extraction operation and fast algorithm for convolution operation.)

滚动轴承信号的保罗谱分析，hilbert Teager能量算子，信号平方，信号取绝对值等等方法求信号包络谱(hilbert transmission)

用有限差分方法求解波动方程，画出波场快照，模拟波在地下传播！(The wave equation by finite difference method, draw the wave field snapshot, simulate wave propagation in the underground!)
