MATLAB Help:

Write a program that will collect one positive integer from the user. Validation is required. Specifications:

1. The program should collect the input as a string and convert it to a numeric number

2. The program will check if the user enters nothing, a non-numeric value, or not a positive integer. It will keep prompting until the user enters a positive integer.

3. Design a prompt/feedback

Functions you may need: isempty(), isnan(), length(), str2double(), str2num()

Thank you for the help!
