高斯消元法的matlab代码

以下是高斯消元法在MATLAB中的代码：

function x = gauss_elim(A, b)
% Gauss Elimination Method
% A: coefficient matrix
% b: right hand side vector

n = length(b);

% Elimination
for k = 1:n-1
for i = k+1:n
factor = A(i,k) / A(k,k);
A(i,k:n) = A(i,k:n) - factor * A(k,k:n);
b(i) = b(i) - factor * b(k);
end
end

% Back Substitution
x = zeros(n,1);
x(n) = b(n) / A(n,n);
for i = n-1:-1:1
x(i) = (b(i) - A(i,i+1:n)*x(i+1:n)) / A(i,i);
end

end
