add element to empty cell with function in matlab

To add an element to an empty cell with a function in MATLAB, you can use array indexing within the function. Here is an example code block that demonstrates this:

main.m
function updated_cell = add_element(cell_array, index, new_element)
% Adds a new element to an empty cell in the given cell_array at the specified index
  if isempty(cell_array{index})
      cell_array{index} = new_element;
  else
      disp('The cell already has an element');
  end
  updated_cell = cell_array;
end

In this function, we pass in a cell_array which is the array of cells that we want to update, an index which tells us where to add the new element, and the new_element that we want to add.

We then check if the cell at the specified index is empty using isempty(). If it is empty, we add the new_element to that cell using array indexing (cell_array{index} = new_element). If it's not empty, we display a message saying that the cell already has an element.

Finally, we return the updated cell_array.

Note that we're using curly braces {} to access the contents of a cell array, while we use parentheses () to index a regular array.
