[Jan Simon]

file = strcat(logpath,'\',filename)
can be improved:
file = fullfile(logpath, filename);
This considers a trailing file separator in the path and different separator for Unix and Windos.

if exist(file), fid = fopen(file,'at');
else, fid = fopen(file,'wt'); end
EXIST(Key) without specifying the type is very slow, because it tests for files, folders, variables, classes, ... Better use "exist(file, 'file')" -- but even better: omit the EXIST and use "fopen(file, 'at+')".
