Calculates the eigenvalues of the Laplacian Matrix, where the Laplacian matrix is the matrix representation of a graph, in this case a phylogeny. When the R package RSpectra is available, a faster calculation can be used, which does not calculate all eigenvalues, but only the maximum and minimum. As such, when using this option, the vector of all eigenvalues is not returned
minmax_laplace(phy, use_rspectra = FALSE)
List with the minimum and maximum eigenvalues
phylo object or ltable
boolean to indicate whether the helping package RSpectra should be used, in which case only the minimum and maximum values are returned
