In numerical linear algebra, the Gauss-Seidel method, also known as the Liebmann method or the method of successive displacement, is an iterative method used to solve a linear system of equations. #include<iostream> #include<conio.h> using namespace std; int main(void) { float a[10][10], b[10], x[10], y[10]; int n = 0, m = 0, i = 0, j = 0; cout << "Enter size of 2d array(Square matrix) : "; cin >> n; for (i = 0; i < n; i++) { for (j = 0; j < n; j++) { cout << "Enter values no :(" << i << ", " << j << ") "; cin >> a[i][j]; } } cout << "\nEnter Values to the right side of equation\n"; for (i = 0; i < n; i++) { cout << "Enter values no :(" << i << ", " << j << ") "; cin >> b[i]; } cout << "Enter initial values of x\n"; for (i = 0; i < n; i++) { cout << "Enter values no. :(" << i<<"):"; cin >> x[i]; } cout << "\nEnter the no. of iteration : "; cin >> m; while (m > 0) { for (i = 0; i < n; i++) { y[i] = (b[i] / a[i][i]); for (j = 0; j < n; j++) { if (j == i) continue; y[i] = y[i] - ((a[i][j] / a[i][i]) * x[j]); x[i] = y[i]; } printf("x%d = %f ", i + 1, y[i]); } cout << "\n"; m--; } return 0; }
