MATLAB: Changing default values for inputdlg()

Question

I'm trying to work out a way such that if a user inputs some values into a dialogue box then exits it, those previous values are saved and then reused as the default values when the user open it again.

I've tried using the command in a loop with variables for the default answers which I then change i.e with m = answer(1). But when I try using variables instead on actual numbers like {'1', '2', '3'}, I get an error saying 'Default Answer must be a cell array of strings.'

Does anyone know how this may be done?

Michael, does this do what you need?

 defaultanswer = {'20','hsv'};
 for ii = 1:2
    prompt        ={'Enter the matrix size for x^2:',...
                    'Enter the colormap name:'};
    name          = 'Input for Peaks function';
    numlines      = 1;
    defaultanswer = inputdlg(prompt,name,numlines,defaultanswer);
 end

I suspect that your variables are numeric, in which case you need to convert to string, using, e.g., the num2str command.
