svpwm的MATLAB仿真实现 ，此程序用于svpwm的S-function的建立(MATLAB simulation implementation of SVPWM)

说明：  通过python语言实现，利用遗传算法求解二元函数最大值(Using Python language and genetic algorithm to solve the maximum of binary function)

阵元间频率增量按对数增加，发射波束不再按距离周期性出现，发射波束图最大值只有一个。相较于阵元间频率增量固定的传统频率分集阵列，log-FDA能够抗距离相关的干扰，而且发射能量不泄露，具有一定的低截获性能。(FDA with logarithmically increasing frequency offset to achieve a beampattern with a single maximum at the target location. FDA radar with uniform interelement frequency offset, its beampattern exhibits maxima at multiple range values. doe tu the multiple maxima, a number of reflectors located at any of the maxima can interfere the target-return, thus deteriorating SINR.)

可以用于在ABAQUS中进行蠕变损失分析(For creep rupture analysis in ABAQUS)

机器人MATLAB m语言，实现关节机器人的运动学正解运算。算(Robot MATLAB M language, realize kinematic joint robot forward kinematics, inverse operation.)

说明：  MATLAB OFDM仿真代码，采用QPSK调制(MATLAB OFDM simulation code, using QPSK modulation)

These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to verify and apply the Puck Failure Criteria using the commercially available finite element package ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented with different post failure degradation schemes EWM/CSE.

说明：  一受均匀拉力的板，中心带贯穿裂纹，裂纹长2a，使用4节点单元计算裂尖应力分布和应力强度因子(A uniform tensile plate with a through crack in the center and a crack length of 2a is used to calculate the stress distribution and stress intensity factor at the crack tip using a four node element)

自适应（ self-adaptive）是指处理和分析过程中,根据处理数据的数据特征自动调整处理方法、处理顺序、处理参数、边界条件或约束条件,使其与所处理数据的统计分布特征、结构特征相适应,以取得最佳的处理效果(Self-adaptive refers to the automatic adjustment of processing methods, processing sequence, processing parameters, boundary conditions or constraints according to the data characteristics in the process of processing and analysis, so as to adapt them to the statistical distribution characteristics and structural features of the processed data, so as to achieve the best processing effect.)

说明：  通过设置参数构建最近邻耦合网络；计算网络的度分布(This program is to create a NN coupled network and calculate the degree distribution of a network.)
