A Note for Bounds of Norms of Hadamard Product of Matrices

In this paper, we have established upper bounds for the spectral norms of Cauchy-Toeplitz matrix and Cauchy-Hankel matrix, with g = 1/2 and h = 1. Moreover, we have obtained an upper bound for the spectral norm of Hadamard product of Cauchy-Toeplitz and Cauchy-Hankel matrices. In addition, we have established an upper bound for the norm of Hadamard product of Cauchy-Toeplitz and Cauchy-Hankel matrices.
