As we know,there are structfun,arrayfun,cellfun and so on.Could we find those function with code method in matlab?
As I try,the help *fun doesn't work.

What about:
FileList = dir(fullfile(matlabroot, '**', '*fun.m'))
But I do not see that this is useful. "Could we find those function with code method": Solve this by opening the docs of e.g. cellfun. Then go to the "See also" line on the bottom and follow the links. You will soon have an overview over all related functions. In opposite to this, knowing that the toolbox path contains "mathfun mech_setup_sfun mfun myfffun myfun mysvmfun myufun ..." is not useful.

While {FileList.name} is elegant, this would be the loop:
for i = 1:numel(FileList)
FileList(i).name
end

Note that this solution requires R2017a or later, as that is the version that added support for as a wildcard in dir()

There is no matlab method to do this or those method will be too complicated??

pathdirs = regexp(path, pathsep, 'split');
funs = {};
for diridx = 1 : length(pathdirs)
thisdir = pathdirs{diridx};
file_info = [dir( fullfile(thisdir, '*.m') );
dir( fullfile(thisdir, '*.p') )];
for fileidx = 1 : length(file_info)
thisfile = file_info(fileidx).name;
[~, basefile, ~] = fileparts(thisfile);
if length(basefile) >= 3 && strcmp(basefile(end-2:end), 'fun')
funs{end+1} = basefile;
end
end
end
funs = unique(funs);
fprintf('%s\n', funs{:});
