Question

5. Consider This special matrix H -[hijlnxn where the entries of H is (a) Construct the matrix H for n 4 and leave all entries as fractions. Use the exact arithmetic to find the exact solution to the system 0 0 0 b, where b . Find the determinant of H (b) Use four-digits rounding arithmetic to express H found from part 0 0 0 (a); then use it to solve the system HT - b, where b - Find the determinant of H (c) Compare the determinant of H from part (a) and (b). What can you conclude about H

***** Use only MATLAB . Don't use "Printf" C programming

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

clc
clear all
n=4;
for i=1:n
for j=1:n
H(i,j)=1/(i+j-1);
end
end
b=[1;0;0;0];
disp('Solution is')
x=H\b
disp('Determinant is');
det(H)
H=round(H*(10^4))/(10^4);
disp('Part b');
disp('Solution is')
x=H\b
disp('Determinant is');
det(H)
