Pca-extraction

有关雷达的使用的Matlab小程序，相当于雷达工具箱，特别是做雷达控制方面的很有用！(This project is very useful to the people who like doing the radar especially doing the radar control.)

可自行设置参数产生SCM信道，支持MIMO等功能(can set your own parameter to create SCM channel,support MIMO an other function.)

改进根升余弦成型滤波，信噪比可达-70dB，性能较标准升余弦提高较大，在TVB2脉冲成型中仿真验证过(Improved root raised cosine shaping filter, SNR up to-70dB, performance than the standard raised cosine larger increase in pulse shaping TVB2 verified in simulation)

才有matlab实现最优化理论的几个重要算法，分别是最速下降法，内点法，外点法，插值法(Matlab to achieve optimization theory have several important algorithms, namely, the steepest descent method, interior point method, external point method, interpolation method)

高效调制信号MPPSK,以及其功率谱特征(Efficient modulation signal MPPSK)

修改了现有的NSCT-tool中的混合C编程部分，所有步骤都通过matlab的矩阵运算完成，提升数倍的运行速度。(Modify existing NSCT-tool in a mixed C programming section, all the steps are completed by matlab matrix operations, increase several times speed.)

matlab code for SegmentTool An Interactive GUI for Segmenting Images

说明：  基于声卡和MATLAB的语音信号采集和处理(MATLAB-based sound card and audio signal acquisition and processing)

无需把图像转换成向量形式，而是将图像看成是矩阵形式，大大减少了计算量。(Without the need to convert images to vector form, but the image as a matrix form, greatly reducing the amount of calculation.)

重装系统后恢复matlab文件关联,重装系统后，若没动MATLAB安装目标，则MATLAB不用重新安装。（同样的原因，可以移动MATLAB安装目标）对MATLAB相关文件，建立重新关联就行了。(Reinstall the system restore matlab file association, reinstall the system, if no action MATLAB installation target, MATLAB without having to reinstall. (For the same reason, you can move MATLAB installation target) on MATLAB related files, to establish re-associate on the line.)
