Question
Many engineering problems can be formulated as a system of linear equations in the form Ax = b Write a Matlab function with the input variables A and b, and evaluate x using the matrix inverse method. (Hint page 3 of the lecture note "Solution of linear equations" and the matlab command "inv".) Write a Matlab function with the input variables A and b, and evaluate x using the Gaussian elimination method. (Hint page 7 of the lecture note "Solution of linear equations" and check the "slash" in matlab.) Write a Matlab function with the input variables A, b and x(0), and evaluate x using the Gauss-Seidel method.(Hint page 10 of the lecture note "Solution of linear equations".)Explanation / Answer
function A = lu_gauss(A)
[n,m] = size(A);
if n ~= m; error(
