You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.

% FT_SAVE_WORKSPACE saves every variable in the base workspace to a .mat file with
% the same name as the variable in the workspace itself. For example, the variable
% "ans" would be saved to the file "ans.mat". Prior to calling this function, you
% might want to clean up your workspace using CLEAR or KEEP.
%
% Use as
%   ft_save_workspace(dirname)
%
% If the directory does not yet exist, this function will create it for you. If you
% leave it empty, the files will be saved to the present working directory.
%
% For example, the following will save all variables to a time-stamped
% sub-directory that is created inside the present working directory:
%
%   ft_save_workspace(datestr(now))
