Answer 1

for a for a vector u=(1,-5,3,-3)€R^4 the infinity norm is???

Answer 2

Answer:

5

infinity norm Gives the largest magnitude among each element of a vector. Having the vector X= [1 ,-5,3,-3], the L-infinity norm is 5.

infinity norm=square root √(1)^2 +(-5)^2 +(3)^2+(-3)^2

as (-5)^2 gives largest magnitude 25

so ans is 5
