Help solving in matlab

Solution

(a)
[x,y] = lu(A)
%% storing into .dat files
save(\'A4.dat\',\'x\',\'-ascii\');
save(\'A5.dat\',\'y\',\'-ascii\');

-------------------------------------------------------------------------------------------------
(b)
b = [0;0;0;0;0;0;0;0;5;0;5;0;5;]
x = A\\b
%% storing into .dat files
save(\'A6.dat\',\'x\',\'-ascii\');

-----------------------------------------------------------------------------------------------
(c)
b = [0;0;0;0;0;0;0;0;5;0;5.1;0;5;]
ans = norm(b,Inf)
%% storing into .dat files
save(\'A7.dat\',\'\'ns,\'-ascii\');
