Hi,
I am working on some continuation problems and need to approximate the null
space of a matrix for bifurcation and branch switching.
Are there algorithms available in Petsc to do this? Can Slepc be used to
calculate the null space of a matrix? I guess the eigenvectors corresponding to
zero eigenvalues would serve this purpose? Literature is pointing me in the
direction of more elaborate Moore-Spence algorithms. I am not sure why an
eigensolver cannot be used for this purpose.
Any guidance would be greatly appreciated.
Thanks,
Manav
