给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列 另外该函数用cos(x)项傅里叶级数展开一个多项式( ChebyshevExpansion.m by David Terr, Raytheon, 5-26-04 Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with highest power on the left, expand f(x) as a sum of scalar multiples of Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.)

模糊c均值聚类的一种改进算法，比较简单。用的时候先初始化一下，在不断迭代，参考里面的main函数吧。参考的时候去掉一些无关的命令，有些命令是我自己调用的无关的命令，可能目录里面没有，但不妨碍这个算法运行，可以屏蔽掉。(an improved fuzzy c means clustering algorithm)

将环境信息转换为栅格模型，便于进行下一步的处理和路径规划(The environmental information is converted into a grid model, convenient for further processing, and path planning )

此程序为本人编写的神经网络法设计1型FIR滤波器的程序，读者读此程序后，可以很深刻地理解如何用BP网络和LMS算法来设计滤波器。 只需更改程序中的H值，即可生成各种低通，高通，带通，带阻滤波器。程序运行结果可得到滤波器系数，幅频曲线和衰减曲线。 可通过更改迭代步长和误差极限来调整滤波器特性。(I prepared for this procedure the neural network type 1 FIR filter design procedures, the reader after reading this program, it is a profound understanding of how to use BP network and the LMS algorithm to design filters. Just change the procedures in H values, to generate a variety of low-pass, high pass, band-pass, band stop filter. Program is running the results of available filter coefficients, amplitude-frequency curve and the attenuation curve. Can change the iteration step size and error to adjust the filter characteristics of the limit.)
