how to assign variables to user inputs

I'm asking the user to input 6 values between 1 and 59, I want to assign variables to each input so they can be compared etc. I think the final line of code may help in doing this but I don't understand what it does?

prompt = {'Enter your first integer between 1 and 59', 'Enter your second integer between 1 and 59', 'Enter your third integer between 1 and 59', 'Enter your fourth integer between 1 and 59', 'Enter your fifth integer between 1 and 59', 'Enter your sixth integer between 1 and 59' };

dlg_title = 'User inputs';

num_lines = 1;

answer =inputdlg(prompt,dlg_title,num_lines);

dlg_answer{1}(1,:)

‘I think the final line of code may help in doing this but I don't understand what it does?’

The inputdlg function returns a cell array of character variables. If you want numbers from it, you may need to use the str2double to produce double-precision floating-point numbers.
