Hello,
indeed I am starting to work with Matlab, please I want a Matlab program for the Gauss method for solving Ax=b (using pivoting).
Thank you

a=[1 5 8;2 -4 10;6 2 -5]
b=[5;1;3]
A=[a b]
n=size(A,1)
for k=1:n-1
for i=k+1:n
w=A(i,k)/A(k,k)
for j=k:n+1
A(i,j)=A(i,j)-w*A(k,j)
end
end
end
A
for i=n:-1:1
s=0;
for j=i+1:n
s=s+A(i,j)*x(j);
end
x(i)=(A(i,n+1)-s)/A(i,i)
end

bonjour.s.v.p je veux un programme qui me permet de résoudre les systèmes d'équations linéaires avec la méthode de Gauss en MATLAB si le pivot est nul merci....
