thank you very much for your post. What about using mxXXX functions like mxGetField? Those should be threadsafe, right?

Greetings, Thomas

function output = report_calltime(input)
persistent storage

if isempty(input)
if isempty(storage)
% create a new structure
storage.parentname = evalin(‘caller’, ‘mfilename’); % get the mfilename of the calling function
storage.time = clock; % get the current time
else
% append to the existing structure
storage(end+1).parentname = evalin(‘caller’, ‘mfilename’); % get the mfilename of the calling function
storage(end).time = clock; % get the current time
end
output = storage;
clear storage
end

You would call “report_calltime” at the beginning of each of your functions. After they are done, you can do “storage = report_calltime(1)” to get the recorded structure.

Note that I did not test the function that I just made up, so it might have some small errors.

J’ai besoin de savoir à quelle heure je lance mon logiciel Matlab (ou exactement j’ai besoin de cela pour chaque M-file)
