Subplotting error with velocity vs time graph
显示 更早的评论
Hi i am having trouble with plotting a graph for velocity vs time. We have to change the velocity from m/s to km/h and the time from seconds to hours. For some reason when we plot them, they are both straight lines along the x axis. This is our code:
subplot(2,2,3)
t=data(:,1);
thour=t/3600
dkm=displacement/1000
vel=dkm/thour;
plot(thour,vel);
title('Velocity Vs Time:')
ylabel('Velocity (km/h)')
xlabel('Time (h)')

vel=dkm./thour;
Need the dot operator here...

That's indeterminate from the info available...but I suspect your formulation of dividing by the time vector may be be the culprit. You probably actually need a constant dt for the base conversion. Dividing by an increasingly smaller t at the origin will eventually lead to 1/0-->Inf which it appears is what you have in the plot.
