超声波测距程序，包含AD采样和信号处理等。(Ultrasonic ranging program, including AD sampling and signal processing.)

说明：  模型以永磁直驱同步发电机组为研究对象，对包括风力机、发电机及其控制系统等各部分进行控制建模与仿真，接着通过坐标变换，分析并网逆变器在d／q坐标系下的模型，采用基于d轴电网电压定向矢量控制，并通过前馈补偿，实现有功、无功的解藕独立控制.(The model takes the permanent magnet direct drive synchronous generator set as the research object, and carries on the control modeling and simulation to each part, including wind turbine, generator and its control system, and then analyzes the model of grid-connected inverter in d coordinate system through coordinate transformation. The voltage oriented vector control based on d-axis power network and feedforward compensation are adopted to realize the decoupling independent control of active and reactive power.)

matlab互相关函数，可用于地震数据处理。(auto correlation of the seismic data)

定步长ODE4、ODE5算法，用法和ode45相似 唯一不同的就是ode45是[t,y]=ode45(), 这个是y=ode4()，因为是定步长的(Fixed-step ODE4, ODE5 algorithms, usage, and the only difference is similar to ode45 ode45 is [t, y] = ode45 (), this is y = ode4 (), because the step length is fixed)
