《计算物理基础》是北师大彭老师写的，对学习用matlab解决物理问题很有帮助(this is a book about Computational Physics used matlab,the author is Mr peng and come from Beijing Normal University)

simple image inpainting using low pass filter. The file removes red text for the image.

说明：  此文件为MATLAB中常用的函数逼近的算法集。所有算法由本人亲自调试通过，且算法风格简介明了，代码格式美观。(This document is commonly used for the MATLAB function approximation algorithm for the set. I personally by all the algorithms, through debugging and algorithm profile style and clear, attractive format code.)

利用matlab对一副图像的灰度值进行扫描运算(Use matlab for gray values ​ ​ of an image scanning operation)

三次样条插值函数，可以直接调用，本人亲测过来，用了matlab现成的函数在里面(Matlab cubic spline interpolation function can be called directly)

QAM数字通信系统仿真程序，包含了发射、调制、编码、信道、解码、解调和接收模块，适合初学者。(QAM digital communication system simulation program, including the launch, modulation, coding, channel decoding, demodulation and receiver module, suitable for beginners.)

软件程序按照发射端所掌握的各用户信道状态信息的程度共分为两部分：即完整信道状态信息(CSIT)和部分信道状态信息(CSIP)。其中，每一部分都包括预编码(precoding)和用户调度(scheduling) 在CSIT中，precoding又按照各用户的数据流数分为单数据流和多数据流两种情况。在每种情况下，首先考察了不同预编码算法的性能表现，包括两种ZF、MMSE、SINR、SLNR。之后又考察了功率分配算法的性能表现（文件名中含有PD表明其含有功率分配的过程）。按照不同指标进行功率分配的，在文件名中进行了区分，如PD_CN代表以信道范数为参考指标进行功率分配。Scheduling部分首先观察了RoundRobin、MaxH和MMSLNR三种算法的性能对比。之后在Kc和Round部分分别观察了不同预选用户数和不同最大替换轮数下MMSLNR算法的表现。 在CSIP中，只对各用户单数据流的情况进行了仿真。采用的预编码算法主要有DSLNR（即直接运用CSIT下的预编码算法）、ESLNR（即对SLNR进行均值计算的，在CSIP中，引入均值计算的与SLNR有关的算法，其文件名中都有modified以示区别）、EMMSE（即陈明老师那边的那篇文章中的预编码算法）。Scheduling中也只是简单的观察了RoundRobin、MaxH、DMMSLNR和EMMSLNR（前者没有均值计算，后者有）的性能对比。(The degree of channel state information for each user software program in accordance with the master transmitter consists of two parts : the complete channel state information (CSIT) and partial channel state information (CSIP). Wherein , each of which comprises a pre- coding (precoding) and the user scheduling (scheduling) In CSIT in , precoding and each user according to the number of data streams into a single data stream and multiple data streams in both cases . In each case , first examine the performance of different pre- coding algorithm, including two ZF, MMSE, SINR, SLNR. After they inspected the power allocation algorithm performance ( file name contains PD showed that it contained power allocation process ) . According to different indicators for power distribution , make a distinction in the file name , such as PD_CN representative channel norm-referenced index for power distribution . Scheduling section first observed the performance comparison RoundRobin, MaxH and MMSL)

说明：  对于非均匀线型阵列，以降低波束方向图峰值旁瓣为目标，在给定阵元数和阵列孔径的约束条件下，利用多种群并行进化遗传算法进行阵元布阵优化。(For non-uniform linear array, in order to reduce the peak side lobe of beam pattern, the multi population parallel evolutionary genetic algorithm is used to optimize the array element arrangement under the constraint of the number of array elements and array aperture.)
