Implementations§

Source §

impl TopologicalFeatures

Source

pub fn from_complex(sc: &SimplicialComplex) -> Self

Extract topological features from a SimplicialComplex.

Source

pub fn signature(&self, len: usize) -> Vec<f64>

Compute a simple topological signature vector of fixed length len.

The signature concatenates (betti_numbers padded/truncated to len/2) and (simplex_counts padded/truncated to len/2), normalised to unit L2 norm.
