The function CollectLikert.m presents a Likert-type questionnaire with radio button responses. The function displays the questionnaire items, records the responses, and returns the responses when the user clicks a "Done" button. If there are too many questions to display on a single page, the function handles paging across multiple pages. The function accepts parameters defining the questionnaire items, the number of rating points on the Likert scale and their labels, the size of the window in which to display the questionnaire, instructions to present with the questionnaire, etc. The function simply returns a one-dimensional array with each number indicating the response to one item.
