Hi, I am trying to find the neig=5 smallest eigenvalues (in magnitude) of a generalised problem (K-val*M)*vec = 0 where K is real symmetric positive indefinite and M is real symmetric positive definite. This is close to a question in a previous thread but here I try to use KrylovKit.jl. My toy …

Smallest magnitude sparse generalized eigenvalues

Not necessarily: in mechanics the fundamental frequency is always non-zero (ie. the first non-zero after the zeros).
