Thread Subject: Passing Cell Array Data to a Structure...

Greetings!

I have a function F that returns a cell array with dimension 1x2. I want to call the function F and at the same time to pass output data to specific fields of early created stucture S, e. g. something like this:

[S.a S.b] = F(...)

Is there any way to do such assignment in MATLAB?

Dear Andrey Kazak!

Yes, it works.
[A, B] = function F
  C = {'a', 'b'}; % Just as example!
  A = C{1};
  B = C{2};
return;

Now you can call F and write the reply in the fields of a struct:
  [S.a, S.b] = F
The field can, but need not exist before calling.
In Matlab 5.3 (perhaps 6.0, 6.1), the fields must exist before.

Good luck, Jan

See CELL2STRUCT and/or DEAL

% your function
F = @() {'hello',2}
% call the function and put them into a (new structure)
S = cell2struct(F(),{'a','b'},2)
% or
C = F()
[S2.a, S2.b] = deal(C{:})
