Write a program to solve a banded linear system of equations using the Gauss-Seidel method.
A user is prompted for the file paths containing the coefficient and constants matrices. The matrices are provided and loaded using csv read. Then the user must use a gauss-seidel method for banded matrices to solve the linear system of equations, and the answers written to a user specified output file (using csv write). The struggle is with the gauss-seidel function, it is not like the typical function in that the coefficient matrix is already banded and not square. It then asks for a function to convert the banded matrix to a full matrix.
