Abstract
We prove estimates for for and any random matrix having the entries of the form , where has i.i.d. isotropic log-concave rows. This generalises the result of Gu\'edon, Hinrichs, Litvak, and Prochno for Gaussian matrices with independent entries. Our estimate is optimal up to logarithmic factors. As a byproduct we provide the analogue bound for random matrices, which entries form an unconditional vector in . We also prove bounds for norms of matrices which entries are certain Gaussian mixtures.
