lsb算法将水印图像按最不重要位(LSB)方法嵌入到载体图像中，在把水印从载体图像中提取出来(This is a LSB algorithm that embedding watermark into the least important part of the primary image, and the watermark can be extracted from the primary image.)

这个函数估计到库默尔与第N系列的广义超几何微分方程解的权力。库默尔的差分方程为： x *的克 （十）+（二- X）的*克 （​ ​ x）的- A *的为g（x）= 0 该代码只有4线长，利用Matlab的向量运算有权采取了第N广义超几何级数的权力的总和。(This function estimates the solution to kummer s differential equation with the first N powers of the generalized hypergeometric series. Kummer s differential equation is given by: x*g (x)+ (b- x)*g (x)- a*g(x) = 0 The code is just 4 lines long, using the power of Matlab s vector operations to take the sum over the first N powers of the generalized hypergeometric series.)

说明：  利用ARMA、AR、MA模型，以及周期图等进行系统参数估计(use ARMA, AR, MA model and cycle map for parameter estimation system)
