The induced matrix norm for a square matrix ##A## is defined as:
##\lVert A \rVert= sup\frac{\lVert Ax \rVert}{\lVert x \rVert}##
where ##\lVert x \rVert## is a vector norm.
sup = supremum
My question is: is the numerator ##\lVert Ax \rVert## a vector norm?
##\lVert A \rVert= sup\frac{\lVert Ax \rVert}{\lVert x \rVert}##
where ##\lVert x \rVert## is a vector norm.
