Variable length of input dialogue box in matlab -

I am using inputdlg in MatLab to enter the cost of the component:

  X = inputdlg (celestial (num2str ((1: n). ',' Input cost of component% d '))); X = str2double (x);  

Where N is not component, it is to create an array of cost. The problem is that it is N , ie N = 13 , then it becomes difficult to view and record the data. I have the 40 component.
