Just curious, did you read the documentation for input() ? >>doc input In the documentation it states: strResponse = input(prompt, 's') returns the entered text as a MATLAB string, without evaluating expressions. The MATLAB doc is pretty thorough, so I do recommend that you read it. It will really help you as you learn MATLAB. It's telling you that if you use the optional second argument, 's', that any input is treated by MATLAB as a string. Even if you enter a number, MATLAB will treat that number as a string. For example: R = input('Enter your name:\n','s'); Enter John and then see what R contains. You can query its class by entering class(R) You will see that R is a character array. Now try R = input('Enter your name:\n'); Enter John again and see what happens. Why did that happen? Finally try: R = input('Enter a number between 1 and 10:\n'); % Enter any number class(R) R = input('Enter a number between 1 and 10:\n','s'); % Enter any number class(R) Wayne
