Hi, all

I need help on calculating induced matrix norm.

I did check wikipedia, but i can't understand the notions they are using.

So can anyone so kindly explain this to me using an example, like compute the induced matrix norm for the following matrix

[1 1 2

2 2 2

1 1 1]

I just made it up...hope it's easy to demonstrate what to do with it

Thank you (Nod)
