For the problems below write well-formatted MATLAB programs. Each program should include a title comment line, a brief description of what the program does, your name as the program author, and separate sections labeled set parameters," "calculate , and display results. Begin each section with a comment line that starts with "%%". Create informative and readable variable names. 1. Greeting. Write a MATLAB program, greeting.m, that asks for the first name of the user and then greets the user. Something like this: What is your first name? Alfonso Good morning, Alfonso! Glad to be computing with you today. 2. Quadratic roots2. Write a program, quadroots2.m, to prompt the user to enter in turn a, b, and c, and then calculate the roots of the quadratic equation. Something like this: *********************************** Quadratic Solver for ax^2+bx+c=0 Please enter a: XX Please enter b: xx Please enter c: xx The roots are: Zl=xxxxx Z2=xxxxx ***********************************
