Nota dell'editore: This file was a File Exchange Pick of the Week

FILEFUN is created in the same spirit as e.g. CELLFUN, in that it repeatedly calls the same function FUN with different arguments, in this case filenames. It will then collect the output(s) of the function into concatenated arrays of the same type as FUN delivers, or encapsulated individually in cell arrays.

The filename argument to FILEFUN may contain wildcards(*) and FILEFUN may optionally traverse subdirectories recursively.

FILEFUN can also be called without the FUN argument, turning it into a recursive wildcard file finder.

See 'help filefun' for extensive help and more examples.

Examples:

Open all figure files in current directory:

filefun(@openfig,'*.fig')

Pick a couple of image files and compute their mean RGB values:

pth=fullfile(matlabroot, 'toolbox', ...
'matlab', 'demos', 'html', filesep);
[filenames,pathname]=uigetfile('*.png','Pick files', ...
pth,'MultiSelect', 'on');
fun=@(fn) squeeze(mean(mean(imread(fn))))';
mn=filefun(fun,strcat(pathname,filenames))
