Example:
Enter the coefficient matrix A:
[7 -3 1; 2 9 -3; 5 4 11]
Enter the constant matrix B:
[21; 37; 15]
The Lower Triangular Matrix L is
1.0000 0 0
0.2857 1.0000 0
0.7143 0.6232 1.0000
The Upper Triangular Matrix U is
7.0000 -3.0000 1.0000
0 9.8571 -3.2857
0 0 12.3333
The solution for Y is
21.0000
31.0000
-19.3188
The required solution X is
