base2fft
根据DFT的基二分解方法,可以发现在第L(L表示从左到右的运算级数,L=1,2,3…M)级中,每个蝶形的两个输入数据相距B=2^(L-1)个点,同一旋转因子对应着间隔为2^L点的2^(M-L)个蝶形。从输入端开始,逐级进行,共进行M级运算。在进行L级运算时,依次求出个2^(L-1)不同的旋转因子,每求出一个旋转因子,就计算完它对应的所有的2^(M-L)个蝶形。因此我们可以用三重循环程序实现FFT变换。同一级中,每个蝶形的两个输入数据只对本蝶形有用,而且每个蝶形的输入、输出数据节点又同在一条水平线上,所以输出数据可以立即存入原输入数据所占用的存储单元。这种方法可称为原址计算,可节省大量的存储单元。附件包含算法流程图和源程序。(err)

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)
