泽尼克拟合算法，包括直角坐标系拟合和极坐标系的拟合，成熟代码，还请放心！(Zernike fitting algorithm, including fitting, fitting and polar coordinates Cartesian coordinates of the mature code, please rest assured!)

Do you need to gain confidence with handling numbers and formulae? Do you want a clear, step-by-step guide to the key concepts and principles of statistics? Nearly all aspects of our lives can be subject to statistical analysis. Statistics: An Introduction shows you how to interpret, analyze and present figures. Assuming minimal knowledge of maths and using examples from a wide variety of everyday contexts, this book makes often complex concepts and techniques easy to get to grips with. This new edition has been fully updated. Whether you want to understand the statistics that you are bombarded with every day or are a student or professional coming to statistics from a wide range of disciplines, Statistics: An Introduction covers it all.

fluent关于蒸发相变的很全的C程序，有详细的注释，对于相关专业的人很重要(fluent the evaporation phase transition is full C program, detailed notes, very important for the people of the relevant professional)

在fortran环境下编写ductile_fracture子程序，可以通过MARC来调用，实现板材成形中破裂过程的可视化(Written in fortran environment ductile_fracture subroutines can be invoked by MARC, realized in sheet metal forming rupture process visualization)

说明：  使用牛顿迭代法求解非线性方程组，程序简单易懂，初学者都能看明白。(Newton iterative method is used to solve the nonlinear equations. The program is simple and easy to understand for beginners.)

用fortran语言读取NC格式的数据,与大家分享，希望能够共同进步哈，谢谢(Used fortran language to read NC data format to share with you, hoping to make progress together Ha, thank you)

lagrange插值,用于分数时延滤波器farrow结构系数求解(Lagrange interpolation for fractional delay filter Farrow structure coefficient solution)

说明：  有两个ARMA过程，其中信号1是宽带信号，信号2是窄带信号，分别用AR谱估计算法、ARMA谱估计算法和周期图法估计其功率谱。(There are two ARMA processes, in which signal 1 is a wideband signal and signal 2 is a narrowband signal. The power spectrum is estimated by AR spectrum estimation algorithm, ARMA spectrum estimation algorithm and periodogram method respectively.)
