Induced infinity norm
Web9 okt. 2024 · Prove that the induced matrix norm $ A _ {\infty}$ is equal to its maximum absolute row sum. This is my first time working through a proof in numerical analysis. Is my workings correct? If not, how do I solve this proof? Any help is greatly appreciated. Suppose the maximum row is obtained from row $k$ of the matrix $A$.
