Suppose the program is to find average of the numbers given by the user. The first step would be to create a dialog box to ask the user the number of numbers to be input. Second step would be to prompt dialog boxes where the user will enter the numbers. Now, here the number of dialog boxes prompted must be equal to the number input by the user in the 1st step. How do I manage the number of prompts?

DIJESH, you could use something like
prompt = 'Enter data: ';
title = 'Data input';
dlg_ans = inputdlg(prompt,title,[1 100]);
data = str2num(dlg_ans{:});
where the user would enter numbers (separated by empty spaces) and thereby avoiding a second input dialog.

It depends what you need to do. With the above approach you can access the individual values as components of the array (e.g. data(1)). In general I would advise against using n different variable names and rather go with arrays.

in the project which i am working on it is necessary to ask any number of forces from the user and then assign it to different variables so that it can be be split into its horizontal and vertical component. If the user inserts 100 forces and their angles, the program will have to seperate out the components of those 100 forces .....
