How to display answer for partial pivoting for Gauss Elimination method

So i am trying to write a code that uses gauss elimiination method through partial pivoting,I was able to get my answers but wasnt sure on how to display my Upper triangular matrix(partial pivoting).Here is my code

A=[8 7 1 0;5 2 -2 2;2 5 1 -2;0 5 -3 1];

b=[22 12 8 5];

n = size(A,1); % Calculating number of equations

A(:,n+1)=b % Creating the augmented matrix

A0 = A

% Elimination process starts

for i = 1:n-1

p = i

% Comparison to select the pivot

for j = i+1:n

if abs(A0(j,i)) > abs(A0(i,i))

U = A0(i,:)

A0(i,:) = A0(j,:)

A0(j,:) = U

end

end

% Cheking for nullity of the pivots

while (A0(p,i)== 0 && p <= n)

p = p+1

end

if p == n+1

disp('No unique solution');

break

else

if p ~= i

T = A0(i,:)

A0(i,:) = A0(p,:)

A0(p,:) = T

end

end

for j = i+1:n

m = A0(j,i)/A0(i,i)

for k = i+1:n+1

A0(j,k) = A0(j,k) - m*A0(i,k)

end

end

end

disp(A0)

x(n) = A0(n,n+1)/A0(n,n)

for i = n - 1:-1:1

sumax = 0

for j = i+1:n

sumax = sumax + A0(i,j)*x(j)

end

x(i) = (A0(i,n+1) - sumax)/A0(i,i)

end

Hi Idris,

I understand that you are trying to display the upper triangular matrix using partial pivoting with Guass elimination method.

Please go through the following MATLAB Answer Accepted answer to know how 'Upper triangular matrix' is being displayed:

Hope this helps resolves your query.
