sort(分类)用法 sort命令选项很长，下面仅介绍各种选项。 sort命令的一般格式为：(sort (Category) use sort command options is very long, only to introduce the following options. The general format of sort order:)

matlab程序，调频脉冲波雷达回波信号检测到速度信息(Radar Speed ​ ​ program)

在空时分组码的MIMO-OFDM系统条件下，对信道，子载波，比特和功率进行分配，仿真结果表明，系统有良好的吞吐量性能(Space-time block codes in MIMO-OFDM system under the conditions of the channel, subcarrier, bit, and power allocation, simulation results show that the throughput of the system has good performance)

说明：  ：针对MP3 编码方式和帧结构进行分析，利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步 骤，很好地实现了水印的自适应嵌入。对于不同的系统要求，还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入，使算法 具有更大灵活性。同时在牺牲一定的嵌入空间前提下，实现了水印信息的自同步。实验表明，对于不同风格的音乐，该水印算法 具有很好的不可听性。(In this paper，the encoding method and the frame structure of MP3 are expounded in detail，a watermark algorithm is proposed based on the scale factor in MP3 frame.By introducing the step of frame altering analysis，the algorithm can realize that watermarks is embedded adaptively.By modifying threshold SNRlim（the ratio of signal to noise），the algorithm can meet different requirements of some system，that is what enable the algorithm to have a bigger flexibility.Based on expense of some embedding positions，the watermark can be embedded with self-synchronization.The experiment results show this algorithm can get a good audio effect with various types of audio.)

给定数的最小二乘拟合以及在给定两组数据下用矩法估计以及用拟和估计得对比(Given the number of least-squares fitting, as well as the two groups in a given data is estimated using moment method and estimated to be as well as a contrast)

有用的SGA的Matlab源代码，求函数的最大值，根据SGA的C代码改变，很容易懂，对SGA 学习很有帮助(useful SGA Matlab source code, the maximum demand function, According to the SGA C code change, it is easy to understand and very helpful to SGA)

这里以橘子和苹果为例，基于拉普拉斯金字塔变换的图像融合(Here to oranges and apples Case，Based image fusion Laplace transform pyramid)

ABAQUS UMAT code 适用于平面应变，轴对称的黏弹塑性线性应变硬化材料，适用于大变形。(The ABAQUS UMAT code applies to plane strain, axisymmetric viscoelastic plasticity linear strain hardening material, suitable for large deformation.)
