I have 90000 time data and 90000 speed data, and the time are equally averaged. I need to calculate the coefficient of variation for every 30 sec and plot it.
Here is my code, and I got 3000*3000 for the coefficient of variation. So I cannot plot it. Does anyone know how to fix it?
a=time;b=speed;n=30;time_aver=reshape(a,n,[]);speed_aver=mean(reshape(b,n,[]));%
time_std=reshape(a,n,[]);speed_std=std(reshape(b,n,[]));%speed_CV=speed_std\speed_aver;plot(time_aver,speed_aver,'LineWidth',2);hold onplot(time_std,speed_std,'LineWidth',2);
