WebIf m= nand one uses the same norm on the domain and the range, then the induced operator norm is a sub-multiplicative matrix norm. Larisa Beilina Lecture 3. Matrix norm. p-norm The operator norm corresponding to the p-norm for vectors is: kAk p = max x6= 0 kAxk p kxk p. In the case of p= 1 and p= ∞, the norms can be computed as: kAk Webare invoked by the statements norm(A,1) , norm(A,2) , and norm(A,inf) , respectively. The 2-norm is the default in MatLab.
