fft的文件，fortran环境下运行！欢迎指正！(fft documents, fortran environment running! Please correct me!)

说明：  此是多峰函数MATLAB程序，多峰函数在解决多峰曲线问题中经常会用到，有此程序代码可以省去很多麻烦。(This is a multi-peak function MATLAB program, multi-peak function, multi-peak curve in the settlement of the question is often used, there is such a code can save a lot of trouble.)

重力异常正演代码，请好好使用它。帮助学习。。。。(Gravity anomaly forward code, please use it well. Help learn)

H无穷大优化算法代码，用于计算固定阶数的控制器参数优化(HIFOO- A MATLAB package for fixed-order controller design and H-infinity optimization)

计算正交各向异性材料（如木材，复合材料等）的弹塑性本构(The elastoplastic constitutive relation of orthotropic materials is calculated)

用MATLAB实现单因素/两因素重复测量方差分析，自带工具包中只有非重复测量的方差分析函数ANOVA。anova_rm实现单因素；rm_anova2实现两因素( function stats = rm_anova2(Y,S,F1,F2,FACTNAMES) Two-factor, within-subject repeated measures ANOVA.For designs with two within-subject factors. function [p, table] = anova_rm(X, displayopt)Single factor, repeated measures ANOVA.)

matpower工具箱中的算例，基于ieee118的最优潮流计算，包含源代码(matpower toolbox example, calculated based on the ieee118 the OPF contains the source code)

说明：  多维随机数的生成方法，一维随机数生成方法，高维随机数的生成方法(Generation methods of multidimensional random number, one-dimensional random number and high-dimensional random number)

空间数据扩边以后做fft并在频率域延拓，可用于求重磁异常(expansion of spatial data and FFT， in the frequency domain extension can be used to find the gravity and magnetic anomalies)

基于Python编写的差分进化原理的带边界条件约束算法(A band constraint algorithm based on differential evolution algorithm)
