截断奇异值分解技术是一种正则化方法，用于不适定问题的数值计算(Truncated Singular Value Decomposition is a regularizaiton method for ill-conditioned problem computation.)

说明：  在进行激光熔覆或者焊接时可用到的移动热源命令流(Command flow of moving heat source available during laser cladding or welding)

利用pid算法控制电机转速，转速可调，数码管显示，初学者实用(Using PID algorithm to control motor speed, adjustable speed, digital display, beginners practical)

说明：  使用有限体积法求解naca0012流场，欧拉方程(Using finite volume method to solve NACA0012 flow field, Euler equation)

说明：  自己编写的期望最大化（EM）算法的MATLAB实现，里面有较为运行方法和程序说明，对新手有很好的帮助( I have written the expectation-maximization (EM) algorithm in MATLAB, which has run more methods and procedures described, there is a good help for the novice)

数值计算实例，主要有LU分解，龙格库塔法，高斯分解法，欧拉法，曲线拟合，曲线插值(Numerical example)

傅立叶变换的C语言实现，可在Turbo C以及Visual C++下实现。(Fourier Transform C language, in Turbo C and Visual C under.)

三次样条插值（简称Spline插值）是通过一系列形值点的一条光滑曲线，数学上通过求解三弯矩方程组得出曲线函数组的过程。本函数中采用第一类边界值(Cubic spline interpolation (referred Spline interpolation) through a series of key points of a smooth curve, mathematically by solving the three-moment equations derived curve function group process. This function uses the first boundary value)
