Because iOS supports an always-connected mobile device that uses other companies’ wireless infrastructure, Apple has needed to place far more restrictions on iOS developers than it ever has on Mac developers (who are able—at least as of this writing—to write and distribute programs with absolutely no oversight or approval from Apple). Even though the iPod touch and the Wi-Fi–only versions of the iPad don’t use anyone else’s infrastructure, they’re still subject to these same restrictions. Apple has not added restrictions to be mean, but rather as an attempt to minimize the chances of malicious or poorly written programs being distributed that could degrade performance on the shared network. Developing for iOS may seem like it presents a lot of hoops to jump through, but Apple has expended quite an effort to make the process as painless as possible. And also consider that $99 is still considerably less than buying, for example, Visual Studio, which is Microsoft’s software development IDE. This may seem obvious, but you’ll also need an iPhone, iPod touch, or iPad. While much of your code can be tested using the iOS simulator, not all programs can be. And even those that can run on the simulator really need to be thoroughly tested on an actual device before you ever consider releasing your application to the public.

信息论是通信的数学基础，它是随着通信技术的发展而形成和发展起来的一门新兴的横断学科。信息论创立的标志是1948年Claude Shannon （香农）发表的论文 “A Mathematical Theory of Communication” 可运用研究随机事件的数学工具——概率来测度不确定性的大小。在信息论中，我们把消息用随机事件表示，而发出这些消息的信源则用随机变量来表示。

Matlab是一种广泛应用于工程计算及数值分析领域的新型高级语言，自 1984 年推向市场以来，历经二十多年的发展与竞争，现已成为国际公认的最优秀的工程应用开发环境。

MATLAB提供了许多矩阵函数。正是因为拥有了为数众多的、完善的矩阵函数，才使得MATLAB具有了强大的功能。
