Algoritma dan Pemrograman: Implementasi Metode Invers Gauss Jordan

Berikut ini adalah algoritma metode invers gauss jordan yang saya buat dalam bentuk flowchart :

Dan ini penerapannya dalam pemrograman java

        {1, 1 , 1},

        System.out.println("");
        System.out.println("Matriks awal :");
        printMatriks();

            return;
        }
        for (int row = 0; row < n; row++) {

                    }
                }
            }
        }
        System.out.println("Hasil Invers: ");
        printMatriks();
    }
    public static void main(String[] args) {
        new InversGaussJordan();
    }
    private void printMatriks() {
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < n; j++) {
                System.out.print(A[i][j] + "\t");
            }
            System.out.print("|\t");
            for (int j = 0; j < n; j++) {
                System.out.print(B[i][j] + "\t");
            }
            System.out.println("");
        }
    }
}
