1. Write a matlab script that asks the user for a word. If the word is not the same as a predetermined password, it should ask again, and keep asking until the user enters the correct password. (Use a while loop to achieve this.) 2. Change your program from exercise 1 so that it also prints out the number of tries used to guess the word. 3. Write a matlab function that uses the low- level formatted read commands (fgetl, fscanf) to read the numerical values from a file (with the format shown below), sum the values, and output the sum to the command window. Be sure to appropriately open and close the file. You can use any text editor (e.g. notepad, textedit, the matlab editor) to create the file. Assume the file look like this: heights 3.2 4.2 3.11 5.3 6
