Index exceeds the number of array elements (1)

First of all I am new to Matlab and have no experience in other programming languages.

Matlab displayed no signs on the right warning bar, but the code isn't running and I can't spot the mistake.

Are there too many input requests ?...

disp('Materialien zum Auswaehlen: Aluminium, Stahl oder Titan')                                                 %Choise of materials
prompt = {'Material eingeben:','Innendurchmesser:', 'Aussendurchmesser:','Laenge des Stabes:', 'Knickfall:'};   %Set material and values
dlg_title = 'Parameter wählen';
defaultinput= {''};
user_input = inputdlg(prompt,dlg_title,1,defaultinput);
if isempty(user_input),return,end
user_material = user_input{1};                                                                                  %Convert input to string
d = str2double(user_input{2});                                                                                  %Convert iput zu integer
D = str2double(user_input{3});
laenge = str2double(user_input{4});
Knickfall = str2double(user_input{5});

Following Error gets displayed:

FRBA

Materialien zum Auswaehlen: Aluminium, Stahl oder Titan

Index exceeds the number of array elements (1).

Error in inputdlg (line 260)

if ~ischar(DefAns{lp})

Error in FRBA (line 7)

user_input = inputdlg(prompt,dlg_title,1,defaultinput);

While I don't speak that language, I believe your problem is with having defaultinput as a different size to prompt.

Note the following documentation.

If you change defaultinput as follows that should sort you out

defaultinput= {'','','','','',''};
