Question: Write a function namedaxb1 group#.mthat takes the matrix of coefficients Aand the vector?bas input and returns the solution vector?xas an output. The function should have three input arguments:
1) the matrix of coefficientsA,
2) the vector of right- hand-sides?band
3) the tolerancee.
The function should have two output arguments:
1) the solution?xand
2) the number of iterations.
