用matlab检测超声传感器的距离信息数据并实时曲线显示。-Ultrasonic sensors with matlab test data and real-time curve from the information display.

利用M文件画出一条正弦曲线和一条余弦曲线，其中第一条曲线采用红色实线并用+号显示数据点位置，第二条采用黑色点线并用*号表示数据点位置,并标注标题和横纵坐标-Use M file draw a sine curve and a cosine curve, wherein the first curve with red solid line with the+ sign and position data, the second black dotted line with an asterisk

对力传感器测量到的力信号进行滤波，并得到更平滑的曲线，更清晰的显示数据走势，可用于各种带有噪声的信号绘图处理(The force signal is filtered by force sensor, and smoother curve is obtained. It shows the trend of data more clearly, and can be used in various signal drawing processing)
