How to find those function end with *fun

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.

[Steven Lord]

I'm curious. Why do you want to generate such a list?

Answer 1

[Jan]

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.

Perfect..

+1 very neat.

Could you tell me how to show those funciton name?I have try

for i FileList
    FileList(i).name
end

And

deal(FileList(:).name)

But they don't work..

[Stephen23]

FileList.name

or

{FileList.name}

And read this to know why:

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()

[Walter Roberson]

Including package methods and including examples, but excluding built-ins, and excluding methods of object classes that are built into the constructor .m files, the available functions as of R2017a are

Afun aggregatebykeyfun aggregatefun ambgfun arrayfun

basisfun bowlpeakfun bswfun bsxfun

cellfun cgfun chunkfun clientfun code_chart_header_file_sfun code_chart_source_file_sfun code_machine_header_file_sfun code_machine_source_file_sfun confun cwtftboxfun

Thanks again,but actually I wonder know more how do you find it rather the answer directly.

[Walter Roberson]

I used standard Unix tools.

!find /Applications/MATLAB_R2017a.app -type f -name \*.[mp] -print | awk -F/ '{print $NF}' | sort -u

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

[Walter Roberson]

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{:});
