Assigning multiple variables to inputdlg's output string

Hi,
I need to have the user enter multiple values and then for each value to be assigned as a number to a variable.
The current code I have is:
prompt = {'Enter value 1','Enter value 2','3','4','5','6'};
dlg_title = 'Enter values';
num_lines = 1;
defaultans = {'1','5','5','7','2','11'}
Params = inputdlg(prompt, dlg_title, num_lines, defaultans);
[a,b,c,d,e,f] = str2double(Params{:});
However this gives the error:
Error using str2double
Too many input arguments.
Any help would be great, thanks.

prompt = {'Enter value 1','Enter value 2','3','4','5','6'};
defaultans = {'1','5','5','7','2','11'};
Params = inputdlg(prompt, 'MyTitle', 1, defaultans);
C = num2cell(str2double(Params));
[a,b,c,d,e,f] = C{:}
a =
1
b =
5
c =
5
d =
7
e =
2
f =
11

+1: Perfect. I'm not sure if the indirection over num2cell is faster, but it is much nicer than a subfunction with a loop and varargout.

data = str2double(Params);
If you really want to split this to 5 variables:
a = data(1);
b = data(2);
c = data(3);
d = data(4);
e = data(5);
But either use smarter names for the variables or keep them as a vector, if it matchs the underlying problem.
[EDITED] If you really want to split the vector to different variables, you can do this with a small function:
function varargout = SplitToVars(data)
if nargout ~= numel(data)
error('Number of inputs does not match number of outputs.');
end
for iVar = 1:numel(data)
varargout{iVar} = data(iVar);
end
end
