WebIf A is a multidimensional array, then vecnorm returns the norm along the first array dimension whose size does not equal 1. 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.
