MATLAB: Can you use cell or struct as function input？

function

Or can you use cell or struct as function output？

Thanks！

Yes, and yes.

I'm puzzled that you're asking this here when you could quite easily test for yourself... Part of the process of coding is trying things out. Have faith that this process usually does not break your computer.

function [output] = AnswerMyQuestion( input )
  output = input;
end
% Can I pass structs in and out of functions?
result = AnswerMyQuestion( struct('astring', 'value', 'anumber', 1) ) );
disp(class(result));
% Can I pass cells in and out of functions?
result = AnswerMyQuestion( cell(3,3) );
disp(class(result));

MATLAB: Creating an array of structs and using the field directly

It is not clear why you need to structure at all, as the output is simply a cell array with some numeric scalars in it (Octave code below)

>> {[struct('field',1) struct('field',2)].field}
ans =
{
  [1,1] =  1
  [1,2] =  2
}
>> {struct('field',{1,2}).field}
ans =
{
  [1,1] =  1
  [1,2] =  2
}
>> {1,2}
ans =
{
  [1,1] =  1
  [1,2] =  2
}

If the input is already a structure, then you can simply access the field values using the methods given in the documentation for non-scalar structures:

{X.field}
