复合材料的优化,内容里边有很好的描述以及很多的计算实例,适合进阶学习(Objective of this Matlab s program was researched optimization analysis of laminated composite plates for determined the ultimate strength and stress effects of plate s under the regular and uniform out-loads. Therefore, generally Reissner s flat and thick shell finite element model (4Node-20Dof) was developed with first-order shear deformation theory (FSDT). Kirchhoff s classical laminate plate theory yields in adequate results for thick plates (a/th<20). This classical laminated plate (CLPT or CPT), was one of the first developed by Reissner with shear deformation theory. Afterwards, Mindlin was utulizated this shear deformation theory to accommodate rotary of inertia terms on per unit freedom. If this plate system s be very thick (a/th<10) than it is fail to shear deformation-motion and it s condition of adaptive shear stress on plate s top and bottom surface. While this conditions was produced on plate s segment when requered the shear correction factor of shear locking eff)

S－函数是System function 系统函数的简称，是指采用非图形化（即计算机语言，而非Simulink 系统模块）的方式描述的功能模块。在MATLAB 中，用户除了可以使用MATLAB 代码编写S－函数以外，还 可以使用C、C＋＋、FORTRAN 或Ada 语言编写S－函数，只不过用这些语言编写程序时需要用编译器生成 动态连接库（DLL）文件，然后在Simulink 中直接调用(S-function System Function system function, refers to the use of non-graphical (ie computer language, rather than the Simulink system module) way described functional modules. In MATLAB, the user can use MATLAB code to write the S-function outside can use C, C++, FORTRAN or Ada language preparation of the S-function, only in these languages ​ ​ to write programs need to use the compiler to generate dynamic link library (DLL ) file, and then called directly in Simulink)

图像阈值分割技术在图像分割中具有重要的意义。遗传算法既可以对全局信 息高效利用，也减少了存储空间和计算量。利用遗传算法的优点，提出了一 种用改进遗传算法的图像分割的方法，可以将父代中适应度大的个体代替当前代 中的个体，保证了可以选出最优的个体。遗传算法是具有鲁棒性和自适应性的搜 索方法.通过实验对比，表明该方法具有快速、稳定分割的特点。(Image threshold segmentation technology is of great significance in image segmentation. Genetic Algorithms can be used for global information Efficient utilization of information also reduces storage space and computation. Based on the advantages of genetic algorithm, a new genetic algorithm is proposed. A method of image segmentation based on improved genetic algorithm can replace the current generation with individuals with large adaptability in the parent generation. The individual in the system ensures that the best individual can be selected. Genetic Algorithms are Robust and Adaptive Search The experimental comparison shows that the method has the characteristics of fast and stable segmentation.)
