A Simple Generalization of a Result for Random Matrices with Independent   Sub-Gaussian Rows
  In this short note, we give a very simple but useful generalization of a result of Vershynin (Theorem 5.39 of [1]) for a random matrix with independent sub-Gaussian rows. We also explain with an example where our generalization is useful.
