    • Method Detail

      • isNegligible

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