三自由度仿真
本Matlab程序对需要高速穿越大气层的返回舱进行了纵向三自由度的模拟计算，只需输入如下基本参数，初始速度，再入高度，再入角。程序中有比较详细的说明。大气模型采用了真实的1976年美国标准大气模型，内附计算标准大气模型的Matlab程序，只需输入高度和高度间隔即可求出详细的参数值。(The Matlab program calculates the longitudinal three degrees of freedom of a reentry module that requires high speed passage through the atmosphere. Only basic parameters such as initial velocity, reentry height and reentry angle are entered. There are more detailed instructions in the program. The atmospheric model uses the real 1976 American Standard atmosphere model, which contains the Matlab program for calculating the standard atmospheric model. Only the input height and height interval can be used to find the detailed parameter values.)

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.

混合粒子群算法求解TSP问题matlab代码
说明： 混合粒子群求解TSP问题，重新定义了离散粒子群算法DPSO的速度和位置公式,使其适宜求解离散问题.针对DPSO易早熟,收敛慢的缺陷,建立局部极小区域的扰动机制,在结合局部搜索算法PSEC后,提出了一种混合离散粒子群算法HDPSO.(Hybrid particle swarm optimization for TSP)
