说明：  图像融合及其源代码在MATLAB环境下的应用(Image fusion and its source code application in MATLAB )

基于matlab的小波包使用电子书籍。可以方便大家直接使用matlab工具包进行小波变换(based on the wavelet packet Matlab use of electronic books. Can facilitate direct use Matlab tool kits wavelet transform)

说明：  萤火虫算法FA的动态描述。可以展现动态迭代的过程(FA' s dynamic description firefly algorithm. You can show dynamic iterative process)

lle降维，可以参考非线性降维的方法，感觉没lda好用，比pca还行(LLE dimension reduction)

retinex算法 ，基于matlab平台的仿真程序，可以使图像增强。这是已经封装好的程序，有界面，可以直接使用。(Retinex algorithm, based on the simulation program of MATLAB platform, can enhance the image.)

使用基于约束的化学计量模型进行代谢通量可变性分析的例程(The use of constraint-based stoichiometric model of metabolic flux variability analysis routines)

实现图像的直方图,该函数功能强大，已经通过matlab运行(it can realize a image s hist! )

说明：  完成版的LM，稳健的LM检验；空间滞后、空间误差模型的回归，豪斯曼检验。(LM Test for Completed Version;LM test;hausman test;)

function Px = per(x,n1,n2) PER Estimate the spectrum of a process using the periodogram ----------- USAGE Px = per(x,n1,n2) The spectrum of a process x is estimated using the periodogram. x : input sequence n1 : starting index, x(n1) n2 : ending index, x(n2) The periodogram is returned in Px using a linear scale. If n1 and n2 are not specified the periodogram of the entire sequence is computed.

Matlab 符号运算是通过集成在 Matlab 中的符号数学工具箱（Symbolic Math Toolbox） 来实现的。和别的工具箱有所不同，该工具箱不是基于矩阵的数值分析，而是使用字符串来 进行符号分析与运算。实际上，Matlab 中的符号数学工具箱是建立在 Maple 基础上的，当 进行 Matlab 符号运算时，它就请求 Maple 软件去计算并将结果返回给 Matlab。(Matlab symbolic operation is integrated in the Matlab Symbolic Math Toolbox (Symbolic Math Toolbox) to achieve. And different from other toolbox, the toolbox is not based on numerical analysis matrix, but use a string for symbolic analysis and calculation. In fact, Matlab' s Symbolic Math Toolbox is built based on Maple, Matlab symbolic computation to the time when it requests Maple software to calculate and return results to Matlab.)
