13.元胞自动机的matlab程序

matlab有限元分析1D杆结构，2D热扩散问题，2D弹性问题，2D梁受力问题(matlab finite element analysis of 1D bar structure, 2D thermal diffusion problem, 2D elasticity problems, 2D Beams problem)

imx50 pinctrl driver based on imx pinmux core.

说明：  PE是干旱模型中计算相对湿润度的算法，经过测试成功，适合混编！(PE is the drought model to calculate the relative moisture algorithm successfully tested, suitable for mixed!)

下载并显示yahoo finance server实时和历史股票数据，并做相关分析(yahoo finance server stock data downloader)

一种segy格式文件读取，用于地震资料处理，matlab文件。(One kind segy read format for seismic data processing, matlab file.)

说明：  计算数组平均值，以求平均电流，进行异步电机驱动系统逆变器故障检测(Calculate the average value of the array to get the average current and detect the fault of the inverters in the asynchronous motor drive system)

说明：  kasami序列的生成，kasami序列的自相关和互相关特性的分析研究(Generation of kasami Sequence, Analysis and Research on Autocorrelation and Cross-correlation Characteristics of kasami Sequence)

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)}.)

说明：  用函数hough检测直线,程序很好，可以调里面参数。效果很好(Use function houhg to check the line)

利用matlab实现差分脉冲调制，不会的兄弟可以参考一下(Using matlab to achieve differential pulse modulation, the brothers can not refer to)
