i want to solve the partial differential equation
A*y(x,t)'''' + B*d²y(x,t)/dt² + C*dy(x,t)/dt + D*y(x,t) = I(x,t)
' means derivation in respect to x
dt means derivation in respect to t
A,B,C,D are real constants
The input I(x,t) is given as an array I[m][n] which is read in from a file.
I dont know any numerical method to solve this problem. I heard of the finite difference method which is very practicable to solve such problem but i dont know how to applicate it on this equation.
Maybe someone might help me to get forward.
ps. please excuse my horrible english
Thanx to all!
