Problem: Write a MATLAB function which will calculate the roots of a quadratic equation.

Note that:

- MATLAB has a built in function called roots to calculate the roots of a quadratic equation BUT you are required to create your own MATLAB function which performs that calculation.

- Ensure that you state all the assumptions, write all the equations and present flow of your function in your report and pick any example of a quadratic function and compare the results of the function you created with the results of the MATLAB built in function.
