color histogram through RGB components and cloud clustering also

说明：  fdtd 平面波的加入 计算建模 先上传这个，下边的以后补齐(fdtd calculation of plane-wave model to join the first upload of this, after the bottom of the padded)

包括灰级窗和直方图，中值滤波。灰级窗成功的显示需要的切片，直方图采用多种方法来实现对一幅图片的灰度化。(Including the gray-level histogram windows and median filtering. Gray level display window successful sliced need histogram using a variety of methods to achieve a picture of grayscale.)

说明：  近邻传播是一种较新颖的聚类方法，运算量少，聚类速度快。(Affinity Propagation is a new clustering method, which has a low calculation and high clustering speed.)

matlab的小程序 比较简单 应用方便(matlab relatively simple applications of small programs to facilitate)

lfm线性信号的函数实现功能，用于chirp信号的处理(lfm linear function of the signal to achieve functional for chirp signal processing)

比较matlab中ceil()、floor()、round()等的量化误差大小。并比较不同的量化位数的误差(Compare matlab in ceil (), floor (), round (), etc. quantization error size. And comparing different error of quantization bits)

this document a list of mathemtical forms

使用方法，以及一些模型的详细建模方法，方面大家学习交流哈哈(Usage pscad introduction)

按照给定指标采用模拟低通滤波器（巴特沃思低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(Indicators in accordance with a given analog low-pass filter (Butterworth low-pass) to approximate the ideal analog low-pass filter, and then through the bilinear transformation method of digitizing analog filters, the digital filter.)
