Computes Betti numbers: \(\beta_0\) (components), \(\beta_1\)
(loops), \(\beta_2\) (voids), etc.
Arguments
- sc
A simplicial_complex object.
Value
Named integer vector c(b0 = ..., b1 = ..., ...).
Examples
# \donttest{
mat <- matrix(c(0,.6,.5,.6,0,.4,.5,.4,0), 3, 3)
colnames(mat) <- rownames(mat) <- c("A","B","C")
sc <- build_simplicial(mat, threshold = 0.3)
betti_numbers(sc)
#> b0 b1 b2
#> 1 0 0
# }
