    本子程序包含5个子程序,其主要功能是: (1) 子程序CXCY(E,L,IE,JE)的功能 用于计算各单元的杆件的长度及在结构坐标系中的倾角α的三角函数cosα、sinα。 (2) 子程序ELEA(E,L,IE,JE,A)的功能 用于计算结构坐标系下各单元刚度矩阵中的刚度系数。 (3) 子程序TOTAL(E,LNODE,KE,KZ)的功能 用于形成半带宽的结构原始刚度矩阵。 (4) 子程序FIFX(NP,FXI,FXJ,FYI,FYJ,MMI,MMJ,WL,IE,JE)的功能 它是用来计算各单元的等效节点荷载。 (5) 子程序STIFF(E,KE)的功能 (Book program consists of five sub-programs, and its main functions are: (1) subroutine CXCY (E, L, IE, JE) function The unit used to calculate the length of the bar and in the structure coordinates of the angle α of the trigonometric functions cosα, sinα. (2) subroutine ELEA (E, L, IE, JE, A) function Coordinate system used to calculate the structure of the element stiffness matrix stiffness. (3) subroutine TOTAL (E, LNODE, KE, KZ) function Used to form the structure of semi-bandwidth of the original stiffness matrix. (4) subroutine FIFX (NP, FXI, FXJ, FYI, FYJ, MMI, MMJ, WL, IE, JE) function It is used to calculate the equivalent nodal load of each unit. (5) subroutine STIFF (E, KE) function )

    调试所用Matlab版本是6.5,gatbx-toolbox是调试过程中使用的工具箱,有些热心的研友已经提供了该工具箱,之所以再贴一遍,是因为6.5版本下调试该工具箱会出现一些错误提示,在该版本中已经进行了改正,使用该工具箱只需要将压缩包下的gatbx和gatbxTest_fns加入到Matlab搜索路径即可,另外gatbx-origin是Sheffield大学提供的原始版本的工具箱,未做任何改动,两者可做比较之用 3.gatbx-example是算例调试源码和各算例的调试说明,大家可以对照原书进行比较 4.窃以为gatbx工具箱较之Matlab7新版下的gads工具箱更能让人熟悉和了解遗传算法的原理和计算过程,虽然在可视化方面不及gads 5.学习遗传算法如果首先用熟相关工具箱的话,能够先培养信心,然后更有兴趣去专研和了解具体的算法,如果就用现有的工具箱就能解决问题的话,不了解其详细的算法也未尝不可,毕竟不是每个研友都能向see_moonlight那样开发自己的工具箱吧, ( The debugging uses the Matlab edition is 6.5, gatbx-toolbox debugs the toolbox which in the process uses, somewhat warm-hearted ground the friend already to provide this toolbox, the reason that pasted again, was because under 6.5 editions debugged this toolbox to be able to present some wrong prompts, had already carried on the correction in this edition, will use this toolbox only to need to compress package of under gatbx and gatbx Test_fns joins to the Matlab search path then, moreover gatbx-origin was the primitive edition toolbox which the Sheffield university provided, has not made any modification, both might make the comparison are the example debugging sound code and various examples debugging explained with 3.gatbx-example, everybody might compare the original bookCarries on comparison 4. in my opinion under the gatbx toolbox s to be able to let the human compared with Matlab7 update gads toolbox be familiar with the understanding genetic algorithm principle and)
