N = vecnorm (A,p) calculates the generalized vector p-norm. N = vecnorm (A,p,dim) operates along dimension dim. The size of this dimension reduces to 1 while the sizes of all other dimensions remain the same.
WebI have a 2D matrix and I want to take norm of each row. But when I use numpy.linalg.norm(X) directly, it takes the norm of the whole matrix.. I can take norm of each row by using a for loop and then taking norm of each X[i], but it takes a huge time since I have 30k rows.. Any suggestions to find a quicker way?
