nt Five MATLAB Programming Skills >> A = myLoan (100000,-5) Problem Two: (Based on Attaway, Chapter 4, Exercise 15) In chemistry, the pH of an aqueous solution is a measure of its acidity. The pH scale ranges from 0 to 14, inclusive. A solution with a pH of 7 is said to be neutral, a solution with a pH greater than 7 is basic, and a solution with a pH less than 7 is acidic. a) Write a script that prompts the user for the pH of a solution, and prints (use disp) whether it is neutral, basic, or acidic. If the user enters an invalid pH, an error message will be printed. b) Modify the script in Part (a) to accept a row vector as an input from the user. Test the scripts in (a) and (b) using the following user's responses: 5, 11, 16, [2 5 12 9], [3 711 15]. Problem Three: (Based on Chapra, Chapter 3, Problem 3.14) Piecewise functions are sometimes useful when the relationship between a dependent and an independent variable cannot be adequately represented by a single equation. For example, the Problem Two: (Based on Attaway, Chapter 4, Exercise 15) In chemistry, the pH of an aqueous solution is a measure of its acidity. The pH scale ranges from 0 to 14, inclusive. A solution with a pH of 7 is said to be neutral, a solution with a pH greater than 7 is basic, and a solution with a pH less than 7 is acidic. a) Write a script that prompts the user for the pH of a solution, and prints (use disp) whether it is neutral, basic, or acidic. If the user enters an invalid pH, an error message will be printed. b) Modify the script in Part (a) to accept a row vector as an input from the user. Test the scripts in (a) and (b) using the following user's responses: 5, 11, 16, [25 129], [37 11 15].
