function pth = ffpath(fname)

%   FFPATH    Find file path

%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% The function browses very fast current directory and directories known in 

% 'matlabpath' and the system variable 'path'. It searches for the file,

% name of which is in the input argument 'fname'. If a directory is found, 

% the output argument pth is filled by path to the file name from the input

% argument, otherwise pth is empty.

% File names should have their extensions, but MATLAB m-files.

% 

% Arguments:

%   fname   file name 

%   pth     path to the fname

%

% Examples:

%   pth = ffpath('gswin32c.exe')

%   pth =

%   c:\Program Files\gs\gs8.60\bin\

%

%   pth = ffpath('hgrc')

%   pth =

%   C:\PROGRA~1\MATLAB\R2006b\toolbox\local
