Quiz question 8
Check your answer to question 8 as you
may be eligible for an extra mark.
Upon reflection, I think that question 8
was a bit unfair as many of you used the reasoning that the 1-norm is the max
row sum and the infinity-norm is the max column sum. That applies for a matrix.
In the case of a vector the 1-norm is the sum of absolute values of the vector
elements and the infinity norm is the absolute largest value.
In any case if you lost marks
on question 8. by inverting the correct values for the 1-norm and infinity-norm
hand your quiz back to me or Henry Xiao and we will award you an additional
point.
