粒子滤波的另一个matlab程序，能够直接运行，在93年那篇经典论文的基础上，进行了改进(improved particle filter )

许多生产计划与管理问题都可以归纳为最优化问题, 最优化模型是数学建模中应用最广泛的模型之一,其内容包括线性规划、整数线性规划、非线性规划、动态规划、变分法、最优控制等. (matlab matlab matlab matlab optimization)

改进FAST-ICA采用3阶牛顿进行迭代，收敛速度更快(Improvements of the FAST-ICA order 3 Newton iterations, convergence is faster)

说明：  粒子群算法初步讲解，粒子群算法分类，标准粒子群算法的实现(Preliminary analysis of particle swarm optimization)

幂法是一种计算矩阵主特征值（矩阵按模最大的特征值）及对应特征向量的迭代方法，特别适用于大型稀疏矩阵。 但是，一般幂法迭代向量v的各个不等于零的分量将随k 趋向于无穷大而使计算机溢出。因此，我们必须对某通幕法进行规范。即规范化幂法 (Power Method is a calculation of the main eigenvalue matrix (matrix according to the largest eigenvalue modulus) and the corresponding eigenvector of the iterative method, especially for large sparse matrix. However, the general power-law iteration vector v is not equal to zero all the components will be as k tends to infinity overflow of the computer. Therefore, we must pass a law to regulate screen. That is, standardized Power Method)

可以进行直方图计算，也可以进行灰度运算，可以实现图像的变换操作(Histogram can be calculated, it can be gray-scale operation, the image transformation operation can be achieved)

Least squares sinusoid fit algorithm described in IEEE Standard for Digitizing Waveform Recorders (IEEE Std 1057): Algorithm for three-parameter and four-parameter least squares fit to sinewave data using matrix operations. The algorithm is (in most cases) really quick. If the signal frequency is a guess, it has to be close to true frequency value. For further information, consult IEEE Std 1057 and/or IEEE Std 1241 documentation. Now also fits complex sinusoids i.e. phasors with noise and o
