Show that, for any subordinate matrix norm on RnĂ—n, the norm of the identity matrix is 1
Added by Liam L.
Step 1
Step 1: Start with the definition of the subordinate norm, which is defined as the supremum over all vectors x with norm 1 in the vector norm: \[ \|A\| = \sup_{\|x\| = 1} \|Ax\| \] Show more…
