Function Documentation

bool bats::zigzag::detail::lex_cmp(const bats::SimplicialComplex &X, size_t dimi, size_t i, size_t dimj, size_t j)

Compare simplices in lexicographical order looking at largest vertex first (v_0,…,v_p) < (w_0,…,w_q) if v_p < w_q

compare simplex i in dimension dimi with simplex j in dimension dimj

Parameters

• X – simplicial complex

• dimi – dimension of first simplex

• i – index of first simplex

• dimj – dimension of second simplex

• j – index of second simplex

Returns

true if first simplex < second simplex, false otherwise
