MATFOR FFT Visual Fortran program. MATFOR Extensions, as implied in the name, are data or components external to MATFOR modules that can be used to add versatility to MATFOR programs. Currently there are two types of extensions available with MATFOR, they are MATLAB Interface and Tecplot FileIO. MATLAB Interface, a new feature in MATFOR 4.1, provides MATFOR users access to MATLAB functions so they can obtain functionality that has not been built into MATFOR. The ability of using MATLAB functions makes MATFOR an ideal tool for those who create prototypes using MATLAB, then do implementation in C++ and other programming languages. Through the use of MATFOR, users may perform quick results comparisons between MATLAB and other languages.

Abstract-The effect of the companding process on QAM signals has been under investigation for the past several years. The compander, included in the PCM telephone network to improve voice performance, has an unusual affect on digital QAM data signals which are transmitted over the same channel. The quantization noise, generated by the companding process which is multiplicative (and asymmetric), degrades the detectability performance of the outermost points of the QAM constellation more than that of the inner points. The combined effect of the companding noise and the inherent white gaussian noise of the system, leads us to a re-examination of signal constellation design. In this paper we investigate the detectability performance of a number of candidates for signal constellations including, a typical rectangular QAM constellation, the same constellation with the addition of a smear-desmear operation, and two new improved QAM constellation designs with two-dimensional warpi

This assignment requires you to complete the dynamic drawing components of the Date/Time Control Panel from the previous two programming assignments. In particular, you will be moving the map found in the "Time Zone" tab when the time zone changes and will be drawing a clock face corresponding to the time setting.

Advanced UNIX Programming is the long-awaited (19 years!) update to the 1985 original. Maybe "update" isn t the right word--of the 750-or-so pages in the new book, there are maybe two dozen paragraphs that are unchanged. The original covered about 70 system calls, and the new one covers about 300. （这是Advanced UNIX Programming的附书源码）

非常好的优化算法的书，详细介绍了蚁群算法和粒子群算法以及相关的matlab工具箱，讲了理论和应用给出了工具箱的下载地址。 Swarm intelligence is an innovative computational way to solve hard problems. In particular, particle swarm optimization, also commonly known as PSO, mimics the behavior of a swarm of insects or a school of fish. If one of the particle discovers a good path to food the rest of the swarm will be able to follow instantly even if they are far away in the swarm. Swarm behavior is modeled by particles in multidimensional space that have two characteristics: a position and a velocity. These particles wander around the hyperspace and remember the best position that they have discovered. They communicate good positions to each other and adjust their own position and velocity based on these good positions.

一定要在TC下运行，需要包括一些头文件，如graphic.h 要求：画一辆小车不停地水平从屏幕左边运动到右边，随着每一遍运动，小车高度均匀下降，降到最低后返回最高处 相关函数：delay(),kbhit(),lineto(),moveto(),arc(),circle()等。

（1） 实现一个Point类，该类包含表示坐标的两个int型变量x、y，构造方法Point()和Point(int xx, int yy),返回x值和y值的int getX()和int getY()方法，计算两点间距离的double distance(Point)方法。其中计算平方根用Math.sqrt()方法。 （2） 实现一个Circle类，该类包含表示圆心的Point型变量center，表示半径的int radius变量，以及构造方法Circle()、Circle(int xx,int yy,int r)、Circle(Point c,int r)，返回周长和面积的int perimeter()、double area()方法，返回两个圆是否为同一个圆（返回0）、同心圆（返回1）、相交的圆（返回2）、分离的圆（返回3）、包含的圆（返回4）等关系的int relation(Circle c)等方法。PI值可以用Math.PI常量。 （3） 实现测试上述两个类的ClassTest类。该类在main方法中分别创建若干个Point对象和Circle对象，并调用相关方法，输出方法的返回值，验证其正确性。 （4） 将Point类、Circle类和主类的包名分别调整为p1、p2、p3，并重新运行，验证是否运行正确。
