For example: [varargin{:}] = convertStringsToChars(varargin{:});

This is incorrect: no arrays are being concatenated.
When used on the LHS it refers to the elements of the cell array, just like on the RHS. The only difference is that values are being assigned to those elements rather than extracted from them. This is explained in the section "Assigning to a Comma-Separated List" here:

"What does the varargin function do..."
varargin is not a function, it is a cell array which contains any number of optional input arguments:
"... and what does varargin{:} mean?"
That syntax creates a comma-separated list from the cell array varargin:
So your example is equivalent to this:
[varargin{1},varargin{2},..,varargin{end}] = convertStringsToChars(varargin{1},varargin{2},..,varargin{end});

varargin stands for variable number of arguments. You can input any number of arguments to the function. And these inputs are read by nargin which means the number of inputs.
