Hello I have the following code which doesn't work. The problem is Im trying to compare the value "NaN" which I guess isnt a string?...to the value of X. Let me know how to fix it thanks!
str = input('Please enter a number \n\n','s');
X = str2double(str);
if test == 1
disp('That was not a valid number');
disp('Here is your number')
