C组合辛普森求积分 源程序 ＭＡＴＬＡＢ(C portfolio Simpson integral source for MATLAB)

此书是matlab的基础教程，讲解的比较详细，希望和网友分享(This book is the basis of matlab tutorials, more detailed explanations, hope and friends to share)

说明：  本程序有传统的MUSIC算法和基于分数低阶矩的MUSIC算法 在alpha稳定分布下的性能仿真(this programme contain the performence of traditonal MUSIC algorithm and FLOC MUSIC algorithm under the alhpa steady distrubution)

A tridiagonal matrix system solver

Three phase 17 levels MMC.

Useful tool for rendering and outputting information rich images(This function can be used in place of IMAGE, IMAGESC and IMSHOW, but does so much more. It is fast and displays images as they should be- correct aspect ratio, integer magnification, no axes. In addition, it can return the image as an output variable- useful for saving to disk, texture mapping surfaces, and post-rendering manipulation such as overlaying/combining two or more images. All the MATLAB built-in colormaps are implemented, but without MATLAB s nasty discretization artifacts. Plus, there are many new colormaps which are helpful for viewing more complex data, such as optic flow, likelihoods over images, difference images, segmentations, stereo image pairs (as anaglyphs) and edge-maps with orientation. It also accepts user defined linear and non-linear colormaps.)

直方图均衡化是调整图像的强度来对比度增强技术。

 产生长度为1000的标准正太分布的随机信号，画出时域波形及频谱；  采用u=255的非均匀PCM编码，每符号为8bit，画输入-输出关系图；  计算信号量化噪声比（SQNR）；  信道误码率为10-3；  解码，并画出u律反变换后的信号时域波形及频谱。 扩展要求：  采用均匀PCM、量化级数可变、信道误码率可变。 ( have a standard length of 1000 is too random signal distribution, draw time-domain waveform and frequency spectrum  u = 255 using the non-uniform PCM encoding, each symbol for 8bit, drawing input- output relationship diagram  calculated quantization noise signal than (SQNR)  channel bit error rate of 10-3  decoder, and law to draw u the signal after the inverse transform time-domain waveform and frequency spectrum. Expansion of the requirements:  uniform PCM, quantization level variable, a variable channel bit error rate.)
