Matlab code for the problem
function x = backward_substitution(A,b)
% Function to solve the upper triangular system Ax = b
n = length(b); % size of the system
x = zeros(n,1); % initilizing the x vector
for i = n:-1:1 % for loop to compute x_i
sum = 0; % variable to store the sum i+1 to n
for j = i+1:n % fo loop to compute the sum Aij*xj
sum = sum + A(i,j)*x(j); % computing the sum
end
x(i) = (b(i)-sum)/A(i,i); % computing the ith x value
end % end of for loop
end % end of function

(Use MATLAB) Use Gaussian elimination with backward substitution to solve the following linear system. For this problem you will have to do scaled partial pivoting. The matrix A and the vector b are in the Matlab code shown below A=[3 -13 9 3;-6 4 1 -18;6 -2 2 4;12 -8 6 10]; display(A); b=[-19;-34;16;26]; display(b);
Develop a function QR deceomposition using MATLAB and solve this system Develop a function qr solve that solves an n × n system using the MATLAB reduced QR decomposition, if the matrix is singular, the QR decomposition will complete with no error. Make the return values [x, resid], where resid is the residual Ax -bll2. A large residual will indicate that the matrix is singular or ill-conditioned.
