When you use inputdlg the result is a cell, then use
x=str2double(inputdlg(prompt{1},name));
y=str2double(inputdlg(prompt{2},name));
Do not use ans,because it's a special variale in Matlab

If suppose iam taking string values like "good","bad","excellent","nice" as the input data instead of 0.1,0.2,0.3.....
Then what to do...?
in my code it is not accepting the string values
