将一个被小波包分解的矩阵变成小波结构，根据最高的分解层次，将原图3*level+1块分开赋给矩阵以便单独操作，按从上到下，从左到右的顺序(A matrix of wavelet packet decomposition into wavelet structure, according to the highest level of decomposition, the original 3* level+1 block separately assigned to the matrix in order to operate independently from top to bottom, from left to right order)

非线性整数规划的遗传算法Matlab程序 通常，非线性整数规划是一个具有指数复杂度的NP问题，如果约束较为复杂，Matlab优化工具箱和一些优化软件比如lingo等，常常无法应用，即使能应用也不能给出一个较为令人满意的解。这时就需要针对问题设计专门的优化算法。下面举一个遗传算法应用于非线性整数规划的编程实例，供大家参考！(Matlab genetic algorithm of nonlinear integer programming Usually, the nonlinear integer programming is a NP problem, having the index complexity if the constraint is relatively complex, the Matlab optimization toolbox and some optimization software lingo, etc, for example, are often unable to apply, even if that can be also cannot give a more satisfactory solution.This is where the problem for design optimization algorithm.Here for a genetic algorithm is applied to nonlinear integer programming programming examples, for your reference!)
