我被IGRAPH包計算α和權力中心性的圖形,但我得到這個錯誤計算阿爾法和電源中心性通過的igraph
alpha.cent<-alpha_centrality(graph,loops = F)
Error in .local(a, b, ...) :
cs_lu(A) failed: near-singular A (or out of memory)
pow.cent<-power_centrality(graph,loops = F)
Error in .local(a, b, ...) :
cs_lu(A) failed: near-singular A (or out of memory)
有誰知道這是什麼意思?我能做些什麼來解決它?
