matlab实现人体回波模型创建和短时傅里叶测试(Matlab realization of human echo model and short time Fourier test)

黄永刚单晶体塑性的UMAT原始文件，不是网上流传的版本(huang-crystal plasticity)

说明：  利用MATLAB/Simulink实现侧偏角计算，估计出侧偏角的大小。(MATLAB/Simulink is used to calculate the side Angle and estimate the size of the side Angle.)

使用zernike多项式进行光学像差的拟合，从而进行光学镜面像差的分析，有助于提高光学系统的加工精度。(The Zernike polynomial is used to fit the optical aberration, and the analysis of optical mirror aberration is helpful to improve the machining precision of the optical system.)

质心定位算法实现精度要求低的简单定位，加权质心定位比质心定位定位精度更高一些。(Centroid localization algorithm achieves simple positioning with low accuracy requirement, and weighted centroid localization is more accurate than centroid localization.)

说明：  通过设置不同的参数，创建小世界网络，用于仿真建模。(This program is to create a small world network for simulation.)

说明：  采用Python脚本语言二次开发ABAQUS的前处理模块创建了一个带孔平板模型，实现了参数化建模。(Parametrical model using Python in Abaqus.)

说明：  本模型采用abaqus自带的connector连接单元建模，实现了钉节点的模拟(In this model, the connector unit of ABAQUS is used to simulate the nail node)

说明：  主要可以用来研究疲劳累积循环载荷作用下损伤与断裂问题，(It can be used to study the damage and fracture under the fatigue cumulative cyclic load,)

说明：  极限学习机用于数据建模，可定性定量。代码有相关解释，直接运行。(The extreme learning machine is used for data modeling and can be qualitatively quantified.The code has an explanation and runs directly.)
