这是一份有关matlab开发练习的源程序，希望大家支持下。(This is a practice matlab source development, I hope you will support the next.)

基带数字信号调制方法总结.包括ASK PSK FSK(Baseband digital signal modulation methods are summarized, including ASK PSK FSK)

说明：  该程序通过模仿生物的遗传特点，解决全局最优解的问题(The program solves the problem of global optimal solution by imitating the genetic characteristics of organisms)

calculate Gaussian filter for images using matlab

两点边值问题，微分方程数值解法，数值分析作业(Boundary Value Problems, Numerical Solution of Differential Equations)

可以用来演示傅里叶级数 逐项累加 逼近矩形波的效果(Can be used to demonstrate Fourier series, item by item, accumulative approximation of the rectangular wave effect)

流形学习算法，程序中也包含了多种经典的模式识别算法,如MDS、PCA。(Manifold learning algorithm, the program also contains a variety of classical pattern recognition algorithms, such as MDS, PCA.)

ISODATA算法，模式识别课程的一个作业(ISODATA algorithm, a pattern recognition programs work)

约170勘探地震资料和测井资料的分析和显示功能（加上他们所谓的支持功能）的设置。这些功能读取和写入标准的SEG - Y格式的地震数据，读取和写入测井在LAS格式2.0（也读3.0 LAS格式），并执行许多通常对这些数据类型进行的操作。他们使用标准化的结构来表示地震数据和测井数据，从而使函数调用的简单串联。(A set of about 170 functions (plus support functions called by them) for analysis and display of exploration-seismic data and well logs. These functions read and write seismic data in standard SEG-Y format, read and write well logs in LAS-format 2.0 (also read LAS-format 3.0), and perform many of the manipulations usually performed on these data types. They use standardized structures to represent seismic data and well data and thus allow simple concatenation of function calls.)

连续信号（可以自定义的函数）的FFT效果图，初学者学习的例程，不错(Continuous signal (can custom functions) of the FFT renderings, for beginners to learn the routine, good)
