回复 第2楼 的 nan.xiao:
看了一下igraph的文档,在arpack()中说:
Usage
arpack(func, extra = NULL, sym = FALSE, options = igraph.arpack.default,env = parent.frame(), complex=!sym)
The options argument specifies what kind of calculation to perform. It is a list with the following
members, they correspond directly to ARPACK parameters. On input it has the following fields:
bmat Character constant, possible values: ‘I’, stadard eigenvalue problem, Ax = x; and ‘G’,
generalized eigenvalue problem, Ax = Bx. Currently only ‘I’ is supported.
所以貌似现在还不支持广义特征值分解
