M-orthogonal reorthogonalization of qk failed. Large factor diagonal ratio {2} at shift {3} (attempt {0} of {1}) M-orthogonal reorthogonalization of qk+1 failed with code {0}. M-orthogonal reorthogonalization of qk+1 failed after partial reorthogonalization. M-orthogonal reorthogonalization of qk+1 failed after selective reorthogonalization. Must supply both K and M. K and M must be sparse and double. K and M must be square and the same size. Third argument must be a struct array of options. Shift is outside all intervals. Not all eigenvalues found. Reduce FrequencyRange or increase MaxShift. Factorizations failed possibly because the problem is ill-posed. Mass matrix appears to be indefinite. Found too many eigenvalues in an interval. Adjust the left endpoint of FrequencyRange to avoid a cluster of eigenvalues. Adjust the right endpoint of FrequencyRange to avoid a cluster of eigenvalues.
