doa-estimation

求序列数中的前n个极大值 Matlab.m文件程序 输入行向量，n 输出前n个极大值 以及index(Find serial number in the maximum value of the first n-row vector Matlab.m documentation program input, n output and the maximum value before the n-index)

classification and regression tree algorithm 算法c++实现(classification and regression tree algorithm vc++)

说明：  种子优化算法（SOA）matlab源程序，测试Rosenbrock等三个函数，结果很好，可以借鉴学习(Seed optimization algorithm (SOA) matlab source code, testing three functions, the results very good, can learn to learn)

说明：  本程序实现了4PSK的调制与传输，计算了误码率等性能参数(This procedure achieved 4PSK modulation and transmission, calculated performance parameters such as bit error rate)

以多光谱数据为原始数据，通过空间变换、滤波、融合、纹理及图像处理等手段，提取遥感图像多维、多尺度特征，最终建立面向目标检测、识别和分析的特征空间，并使用NASA的实测数据对方法的性能进行验证和分析。(Multi-spectral data to the original data, through space conversion, filtering tools, integration, texture and image processing, remote sensing images to extract multi-dimensional, multi-scale features, for the eventual establishment of target detection, identification and analysis of the characteristics of the space, and measured using NASA performance of the method for data verification and analysis.)

说明：  直接序列扩频的一个例子，对学习这方面知识，和编程都有很好的帮助(An example of direct-sequence spread spectrum, to learn that knowledge, and programming are very helpful)

说明：  实际的数值是带有符号的，即可能是正数，也可能是负数，数值的正负之分如何实现？ 通过补码表示，且用一位符号位区别其正负即可。 而数值本身可以包括整数，也可以包括小数。那么，在计算机中是如何确定小数点的位置呢？ (The actual value is unsigned, which may be positive, it may be negative, positive and negative values divided how? By complement representation, and with a bit different from the positive and negative signs can be. The value itself can include an integer, it can also include decimals. Then, the computer is how to determine the decimal place?)

matlab的光子晶体的能带计算程序，采用的是通用的平面波展开法。(Matlab photonic crystals can take computational procedures, using the common plane wave expansion method.)
