1. Create a user-defined MatLab function that implements the Gauss elimination method called Gauss_alt. The input arguments would matrix [a] and [b] from linear algebra ([a]*[x]=[b]) and the output [x]. If the input argument [b] is a row vector, the function should be able to transform it to a column vector. Use the augmented matrix for [a b] for all operations in the function. Solve the following set of equations by hand (explain the steps you are following): x₁ + 2x₂ - 2x₂ = 9 2x₁ +3x₂+x₂ = 23 3x₁ + 2x₂ - 4x₂ = 11 Use the function Gauss_alt to validate your hand-calculated solution.
