在secshortest中我希望只得到一条次短路,结果却出来好几条，因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。(I hope that in secshortest only a short time, the result is out of several, so when used to get at short circuit, can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest.)

MATLAB控制系统设计，包含控制系统的数学描述，时频分析及根轨迹绘制(MATLAB Contron System Design)

FDTD仿真喇叭天线，能观察得到其电场在自由空间随时间的分布情况。(FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can interested in antenna designing they can also plot the radiation pattern of this HORN antenna.Just take the field in the outside the mouth of HORN antenna and there do the simple formula to near filed far field transfer and measure it at your band of antenna.Best of LUCK all of you.)

模拟信号在多天线下传输的整个过程，包括调制、过信道、解调、计算误码率等(The analog signal in a multiple antenna transmission the entire process, including modulation, over a channel demodulation, calculate the error rate)

basic ofdm with interlever: The transmitter section converts digital data to be transmitted, into a mapping of subcarrier amplitude and phase. It then transforms this spectral representation of the data into the time domain using an Inverse Discrete Fourier Transform (IDFT). The Inverse Fast Fourier Transform (IFFT) performs the same operations as an IDFT, except that it is much more computational efficiency, and there is used in all practical systems. In order to transmit the OFDM signal the calculated time domain signal is then mixed up to the required frequency.

实现脉冲压缩与相控阵的matlab实现 脉冲压缩雷达发射宽脉冲信号，接收和处理回波后输出窄脉冲的雷达。为获得脉冲压缩的效果，发射的宽脉冲采取编码形式，并在接收机中经过匹配滤波器的处理。脉冲压缩雷达的优点是能获得大的作用距离和具有很高的距离分辨力。(pulse compression&phased array)
