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

Thank u... got the output

[Dimple]

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
