本程序用matlab编写。实现图像的构造编码。压缩包中的PPT介绍构造编码。一个编码程序，一个解码程序。本程序是无损压缩，编码后可压缩掉30 以上。附有图片。程序有必要的注释。(This program written by matlab. The structure of image coding. PPT introduced compressed package structure encoding. A coding process, a decoding program. This procedure is lossless compression, encoding more than 30 after the compressible out. With pictures. Program has the necessary comments.)

AX.25是一个数据打包协议，用于信号数据提供高效率的传输(AX.25 is a data package protocol for signal data to provide efficient transmission)

MATLAB编写的卡尔曼滤波实现圆周运动物体跟踪还有图形演示，包括实验代码和实验报告。(Kalman filter to achieve a circular motion object tracking)

建立了单相H桥逆变器单极性PWM调制仿真模型，运行效果良好(A unipolar PWM modulation simulation model of single-phase H bridge inverter is established, and the running effect is good)

八阵元均匀圆阵波束赋型LCMV算法，形成三维方向图(Eight-membered uniform circular array beamforming algorithm LCMV, a three-dimensional direction in FIG.)

说明：  此程序是变型PID控制算法的仿真程序，采用了变速积分方法，系统偏差大时，积分作用应减小，反之应加强。变速积分可以根据系统误差大小改变积分速度，提高了系统品质。(this procedure is a change in the PID control algorithm simulation program using the variable integration method, the system deviation, the integral role should be reduced, on the contrary should be strengthened. Integral variable speed system error can change the size of integration of speed, quality of the system.)

SVPWM仿真用simulink，基本出来了(svpwm)

说明：  水蒸气和水的密度和焓值拟合，主要是减温水的性质描述。(And water vapor density and enthalpy values were mainly described by the nature of warm water.)

本函数用于实现开槽式圆波导TM模式的计算(calculate the cutoff frequency of 2D-circle waveguide)
