eigen vector for generalised eigen pblm.

eigen vector for generalised eigen pblm.

eigen vector for generalised eigen pblm.

(OP)
hi,

i have a generalised eigen value pblm,which is of form (A-λB)x=0... so i converted it to std eigen format, now the pblm is (B^-1.A-λ.I)y=0... how do i transform the eigen vectors of this std format to the eigen vectors of 'x'.

thanks.

Eigen vectors isn't this Applied Mathematics ?
Never used since my University days.

RE: eigen vector for generalised eigen pblm.

(OP)
hi, i am trying to solve the vibration(free) of a portal frame by hand, i calculated the eigen values and calculated the eigen vectors for the std eigen problem, how do i get the eigen vectors for the generalised eigen problem to finally arrive at modeshapes.i cross checked the timeperiod using staad and its exactly matching, so no doubt in the [K] and [M] matrices.
