Lectures on Random Matrices

WebRandom matrices are widely and successfully used in physics for almost 60-70 years, beginning with the works of Dyson and Wigner. Although it is an old subject, it is constantly developing into new areas of physics and mathematics. It constitutes now a part of the general culture of a theoretical physicist.

Can we Generate a Random Matrix with No Repeated Elements

Web8 de nov. de 2024 · Accepted Answer: Bruno Luong. I'm aware of randperm, but it gives vectors rather than 2D matrices. One may also use a loop with randperm to generate a random matrix with no repeated elements in each row, but overalll, this doesn't guarantee the non-redundancy of any element if we consider the whole matrix.
