Hi,

i have a 3D dynamic problem, where in the equation is in the below form

[M]x" + [C]X' + [K]x = [F]

[M], [C], [K] are 3x3 matrix

[F] is 3x1 matrix. x, x', x" are fuctions of t and derivatives. those are again 3x1 matrix

now i want it to feed this data into matlab.

convert through laplace

solve it

and inverse laplace to be done.

i am very much new to matlab. nd any one help me
