Let $A=$hilb$(n).($a$)$ What is the condition number of A when $n=11?$ In Matlab,

type the statements

$rng(20)$;$x=$randn$(11,1)$;$b=A**x$;$=\frac{A}{\frac{?}{?}}b$;$e\frac{?}{a}=bs((x-)\frac{.}{x})$;

What are the positions of the most accurate and least accurate components of $?$

What are the relative errors of those two components? Use scientific notation with $3$

significant digits. $($b$)$ How many correct leading digits are in those two components

of $?$

Use MATLAB software to solve this question.
