In this paper, we gives an upper bound estimation of the spectral norm for matrices \(A\) and \(B\) such that the entries in the first row of \(n\times n\) \(r\)-circulant matrix \(A = Circ_r(a_1; a_2; ...; a_n)\) and \(n\times n\) symmetric \(r\)-circulant matrix \(B = SCirc_r(a_1; a_2; ...; a_n)\) are \(a_i = P_i\) or \(a_i = P^2 _i\) or \(a_i = P_{i-1}\) or \(a_i = P^2_{i-1}\), where \(\{P_i\}^\infty_{i =0}\) is Padovan sequence. At the last section, some illustrative numerical example is furnished which demonstrate the validity of the hypotheses and degree of utility of our results.
