David,
I am not sure about the mathematical formulation of this problem using
pseudo inverse.
So far I know, cholesky decomposition is used for B when (inv(B)*A) is
not symmetric.
In MATLAB, [V, D] = eig(A, B, flag) can be used, where flag ='chol' is
by default for 'cholesky decomposition'
for symmetric A and symmetric positive definite B.
Otherwise, flag='qz' ignore any symmetry and works for non-symmetric A & B,
which is mostly likely same as in LAPACK function that Arttu provided
before:
