Hello everybody,

Can anyone tell me how do I solve the following
kind of problem using Octave :

solve for w in the equation :
        
        __4       2  __2
        \/ w  -  a * \/ w  =  F(t)

where: F(t) is an arbitrary time functon,
       'a' is a function of w(x,y,t),
       and 
       __2                          del^2     del^2
       \/  == Laplacian operator = ------- + -------- 
       __4                         del x^2    del y^2
       \/  == Biharmonic operator.

Assume that the required initial conditions are given
(at least for the time being)

[I hope the formatting remains alright.]

Regards,
Santanu Chatterjee.
