An approach of constructing bivariate orthogonal multiwavelet function is presented by a given bivariate orthogonal uni-wavelet function.The bivariate orthogonal multiwavelet function is a linear combination of the given bivariate orthogonal uni-wavelet function,the multiwavelet is not unique.Bivariate orthogonal uni-waavelet function and any unitary matrix are given,so that we can construct a bivariate orthogonal multiwavelet.
