Hi I have huge set of variables that require an input from the user I would like to prompt them for all of them at once. I cannot figure out how to use inputdlg() from the documentation. I'm currently using,

a = input('prompt')

b = input('prompt')

c = input('prompt')

d = input('prompt')

I want to find a better way to do this. Can someone help?

The only trick for inputdlg() is that it returns a cell array of character vectors and you have to convert the character vectors to numeric if appropriate.

You can use str2double.

How huge is the "huge set of variables"? If your function requires the user to enter hundreds or thousands of values, I would advise you not to require them to use input. Write a function that accepts data passed as input arguments. If you really want to allow your users to type the inputs in manually you can then write a script that calls input and passes that data into the function as input arguments. Users that already have the data in a form your function can accept can bypass the script and directly call the function.
