Solution of system of linear equations
A general linear iterative method for the solution of the system of
linear equations is defined as :
X(k+1) = H*X(k) + c where k = 0,1,2... and
X(k+1) and X(k)) are the (k+1)th and kth iterations for X.
H is called the iteration matrix.
In the limiting case when k -> ∞, X(k) converges to the exact solution. X = A(-1)B
For Jacobi Iteration Method :-
Assumption : Diagonal entries of coefficient matrix A are pivot elements.
H = -D-1*(L + U) and
c = D-1*B where
D is the diagonal matrix, L & U are respectively
lower and upper triangular matrices with zero diagonal entries such that
A = L + D + U
