Can anyone explain me how to solve fourth order ODE equations numerically? or help me in solving the equation in MAPLE software.
Thanks in advance...
Solving higher order DE will determine if the equation in question is:
1. Homogenous
2. Inhomogenous
USING MATLAB TO SOLVE A HIGHER ORDER DE
An example of using MATLAB to solve an inhomogeneous higher order differential equation. The equation is:
yiv)-2yii+ yi=t3+2et
in MatLab:
simply write:
>> syms y
eqn = 'D4y - 2*D2y + Dy = t^3 +2*exp(t)'
eqn =
D4y - 2*D2y + Dy = t^3 +2*exp(t)
The notation D4y means the 4th derivative of y, Dky means the kth derivative (where k is a positive integer).
Solve this equation with the command dsolve, calling the solution, sol.
use the command pretty to print it, which will make it fit appropriatly.
sol = dsolve(eqn);
pretty(sol)
further, to simplify solution,
>>pretty (simplify(sol))
