1、从加载数据开始。load quakewhos e n v
2、Time = (1/200)*seconds(1:length(e))';whos Time
3、varNames = {'EastWe衡痕贤伎st', 'NorthSouth', 'Vertical&垆杪屑丝#39;};quakeData = timetable(Time, e, n, v, 'VariableNames', varNames);head(quakeData)
4、plot(quakeData.Time,quakeData.EastWest)title('East-West Acceleration')
5、quakeData.Variables = 0.098*quakeData.Variables;
6、t1 = seconds(8)*[1;1]挢旗扦渌;t2 = seconds(15)*[1;1];hold onplot([t1 t2],ylim,'k','LineWidth',2)hold off
7、tr = timerange(seconds(8),seconds(15));dataOfInterest = quakeData(tr,:);head(dataOfInterest)
8、figuresubplot(3,1,1)plot(dataOfInterest.Time,dataOfInterest.EastWest)y造婷用痃label('East-West')title('Acceleration')subplot(3,1,2)plot(dataOfInterest.Time,dataOfInterest.NorthSouth)ylabel('North-South')subplot(3,1,3)plot(dataOfInterest.Time,dataOfInterest.Vertical)ylabel('Vertical')
