Creating a matrix that calculates inverse and determinants without using the det and inv commands

Create a function that calculates the determinant and the inverse of a generic 2 X 2 matrix, following the algorithm seen in class (see Lecture 2).
The function should be named invanddet2by2. The function takes a generic 2 X 2 matrix as input, and returns two outputs: the determinant and the inverse. It should do the following few things:
- It calculates the determinant
- If the determinant is zero, the inverse is set to be an empty matrix (i.e. you assign the value [], that's squared brackets with no values inside, which for Matlab means an empty matrix)
- If the determinant is non-zero, then it calculates the inverse according to the 4-steps algorithm seen in class
In the template solution below:
- DO NOT CHANGE UNDER ANY CIRCUMSTANCES THE NAME OF THE FUNCTION
- Add input and outputs in the parenthesis on the first line
- The determinant should be the first output, and the inverse should be the second output
- Add your calculations in the white space below the comments
- YOU CANNOT USE THE MATLAB FUNCTIONS det and inv!!!
