I have to find gradient of norm(x'Ax'b) where x is a vector and A is a 4x4 symmetric matrix. I am trying to solve it by using identities given in https://en.wikipedia.org/wiki/Matrix_calculus but I am not able to figure out which identity suits my problem. I would appreciate if anyone tells me how to tackle this problem.
