isNegligible
boolean isNegligible(Matrix H, int i, int j, double epsilon)
Checks whether a sub-diagonal element is sufficiently small.- Parameters:
H
- a matrixi
- a row indexj
- a column indexepsilon
- a precision parameter: when a number |x| ≤ ε, it is considered 0- Returns:
true
is H[i,j] is deemed small enough
