Matlab中利用双线不变法设计椭圆数字滤波器(Digital filters using two-invariant method designed oval in Matlab)

找椭圆的中心，用得到了很多算法，可以借鉴！(Find the ellipse center, many algorithms have been used, you can learn!)

Lamb波的频散曲线，利用matlab编制了导波曲线，为导波检测模态选取提供了技术工作(Frequency dispersion curve of Lamb wave The guided wave curve is compiled by MATLAB, which provides technical work for the selection of guided wave detection mode.)

说明：  matlab向dsp传递.dat文件的方法，很经典。(dsp matlab to pass. dat file method, it is classic.)

自己开发的基于阶跃响应曲线的面积法程序，实验结果良好。(Their own development based on the step response curve area method procedures, the experimental results well.)

control of boiler with PID Controller

光伏的数学通用模型。 工程用途，我参考搭建的模型 可以使用。(Universal mathematical model of PV. Engineering purposes)

说明：  MATLAB仿真程序，用于数字下变频，并附有代码(For digital down conversion)

LDPC编码调制系统，QPSK编码调制方式，研究生毕业论文源代码(LDPC coded modulation system, QPSK modulation coding, graduate thesis source code)

自由空间E和H场的相位差和振幅衰落，可以显示波形。场特性，方向图，增益等(Free-space E and H field phase and amplitude of the decline can display waveforms. Market identity, direction map, gain, etc.)
