Centro assistenza Centro assistenza. Questo valore equivale a norm X. Calcolare la norma 1 di un vettore, ossia la somma delle magnitudini degli elementi. Calcolare la distanza tra due punti come norma della differenza tra gli elementi del vettore. Creare due vettori che rappresentano le coordinate x,y di due punti sul piano euclideo. Array di input, specificato come matrice o array. Per la maggior parte dei tipi di norma, X deve essere una matrice. Tipo di norma, specificato come 2 predefinito , scalare reale positivo, Inf o -Inf.

Help Center Help Center. Because symbolic variables are assumed to be complex by default, the norm can contain unresolved calls to conj and abs. Compute the 2-norm of the inverse of the 3-by-3 magic square A. Compute the norm of [x y] and simplify the result. Because symbolic scalar variables are assumed to be complex by default, the calls to abs do not simplify.
