MATLAB EXAMPLE CODE FOR POLYALPHABETIC CIPHER

外文原版电子书，详细的讲解了关于matlab和labview在信号处理中的应用。(Original foreign language books, explained in detail on the matlab and labview signal processing applications.)

说明：   提供的文件包含matlab的多个图象处理程序,其中有图象分割,以及图象边缘提取的.(the document contains a number of Matlab image processing procedures, which are image segmentation, and Image Edge Extraction.)

The problem-solving process for a computational problem can be outlined as follows: 1. Define the problem. 2. Create a mathematical model. 3. Develop a computational method for solving the problem. 4. Implement the computational method. 5. Test and assess the solution.

贝克汉函数方便解决一些复杂函数，可以调用作为子函数来使用。(Beckham convenient function to solve some complex functions can be called as a subroutine to use.)

针对MUSIC算法在进行信号波达方向(DOA)估计时谱峰搜索运算量大的问题,提出了一种基于FFT多波束算法与MUSIC算法的联合DOA估计方法。该方法采用FFT多波束算法形成多个波束,近似估计信号DOA,获得对应波束指向,再利用MUSIC算法实现对信号DOA的精确估计。这样就只需在该波束指向对应的空域范围内搜索,减小了DOA估计的运算量。(MUSIC algorithm for performing signal DOA (DOA) estimates peak search operation when big problem, a joint DOA estimation method based on FFT algorithm and multi-beam MUSIC algorithm. The method uses FFT algorithm for multi-beam forming multiple beams, approximate estimate signal DOA, obtain the corresponding beam pointing, reuse MUSIC algorithm for accurate estimation of the signal DOA. This will only search within the beam direction corresponding airspace, reducing the amount of computation DOA estimates.)
