LU Decomposition method

MATLAB codes for LU Decomposition (factorization) method for solving system of linear equations.

For details of the method and also coding watch the lecture: https://youtu.be/SNWiI3a-Di0

Example:

Enter the coefficient matrix A:

[7 -3 1; 2 9 -3; 5 4 11]

Enter the constant matrix B:

[21; 37; 15]
