Using the ODE45 Function in the program Matlab, how would you determine the value of the dependent variable at some value of time?

Solution

write

tspan=[0 20]
y0=[2 0]
[t,y]=ode45[@objectivefun,tspan,y0]

where y will give the dependant variable function values and t is independant variable obj fun has terms like d^2t/dx^2 dt/dx......
