Webord defines the vector norm that is computed. The following norms are supported: where inf refers to float (‘inf’), NumPy’s inf object, or any equivalent object. dtype may be used to perform the computation in a more precise dtype. It is semantically equivalent to calling linalg.vector_norm (x.to (dtype)) but it is faster in some cases. See also 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.
