Matlab input function

  1. Aug 28, 2008 #1
    Hi all,
    Can someone please help me with my matlab code. I am trying to get the program to quite if the user tries to input a non-numeric value, and will display an error message. I have got it to work useing the matlab input('promt','s') command, but i dont want to use this command because a user cant enter 5/100 etc.
    Here is my code.

    Code (Text):
    j = input('number?:')
    if isnan(j)==1
        disp('Input must be a number, Function will terminate')
    I would just like to know if there is a simply way to do this, if not I will use the command I used before and use the eval function I think...

    Thank You

    Regards Elbarto
