Velocity_vs_time graph
显示 更早的评论
I have a code generated in matlab which i am to use of a car coasting down from 120mph => 0mph for velocity against distance, my question is how do i plot velocity against time. I have used an ODE45 function for distance, can i use this method or does and alternative need to be used,
[t,x]=ode45(@frontwing,timerange,initialvalues) plot(x(:,1),x(:,2)) rk=[x(2);-F.rr/mass-Fdrag*x(2).^2/mass]
thanks

v=diff(x)./diff(t); %aproximated derivative
plot(t(1:numel(v)),v)
%I didn't use plot(t,v)
%because the dimensions of t and v might not be the same
