(a) Write a MATLAB Function verifier that . Takes a string (character vector) str as its only input parameter Determines if str is a valid sentence, under the following rules: - It is at least two characters long - It is at at most 1024 characters long - It starts with a capital letter - It ends with a period . Returns either true or false based on the above determination. (b) Write a MATLAB Script tester that: Prompts the user to enter a string (sentence) and store what the user enters into a string variable another variable. Displays a brief report to the screen, which includes the user's input value and the deter- . Stores the result of calling your verifier function, with the user's string as input, into mination of the input's validity based on your function call
