Let the maximum norm (example:
How can we compute the corresponding matrix norm defined as: where x is not equal to 0
I would be grateful if someone show me a step-by-step solution.
Thanks in Advance

An equivalent way of writing the norm is that . Using that definition, let , with . Then , and .
Now think about how to maximise that expression subject to the conditions , , and see if you get the answer 7.
