How do I check if there is a function with the same name

7 visualizzazioni (ultimi 30 giorni)
In addition to the functions that come with matlab, I have added some additional toolboxes, so I want to make sure that there are more than one function with the same name in my directory, who can teach me.

The which function can be helpful.
which which -all
built-in (/MATLAB/toolbox/matlab/general/which)
If there are any others in your MATLAB search path, it should display them as well.

Thank you for your answer, but what I want to do is check if there are any functions with the same name in my path.
The 'which' function seems to only check one by one.

It will detect all of them with the -all flag.
For example, the extremely useful matrix-left-divide (the \ operator) called mldivide, \
which mldivide -all

You can loop over the m-files in your folder, call which(_,'-all') on each one, and store information about what which returned:
F = dir('*.m');
for ii = 1:numel(F)
C = which(F(ii).name,'-all');
F(ii).instances = C;
F(ii).is_duplicate = numel(C) > 1;
end
Then the files that have same-name duplicates somewhere on the path are
D = F([F.is_duplicate]);
and their same-name duplicate locations are given by
D.instances
Example:
% create some folders with m-files
% Folder1 contains file1.m and file4.m
mkdir('Folder1')
fid = fopen(fullfile('Folder1','file1.m'),'w'); fclose(fid);
fid = fopen(fullfile('Folder1','file4.m'),'w'); fclose(fid);
% Folder2 contains file1.m and file2.m
mkdir('Folder2')
fid = fopen(fullfile('Folder2','file1.m'),'w'); fclose(fid);
fid = fopen(fullfile('Folder2','file2.m'),'w'); fclose(fid);
% add the folders to the path
addpath('Folder1','Folder2')
% the current folder contains file1.m, file2.m, and file3.m
fid = fopen('file1.m','w'); fclose(fid);
fid = fopen('file2.m','w'); fclose(fid);
fid = fopen('file3.m','w'); fclose(fid);
% run the code above
F = dir('*.m');
for ii = 1:numel(F)
C = which(F(ii).name,'-all');
F(ii).instances = C;
F(ii).is_duplicate = numel(C) > 1;
end
% F contains info about the files in the current folder
F
F = 3x1 struct array with fields:
name folder date bytes isdir datenum instances is_duplicate
F.name
ans = 'file1.m'
ans = 'file2.m'
ans = 'file3.m'
% D contains info about those files that have same-name duplicates
% somewhere on the path
D = F([F.is_duplicate])
D = 2x1 struct array with fields:
name folder date bytes isdir datenum instances is_duplicate
D.name
ans = 'file1.m'
ans = 'file2.m'
% D.instances tells you where the duplicates are
D.instances
ans = 3x1 cell array
{'/users/mss.system.v6zxt/file1.m' } {'/users/mss.system.v6zxt/Folder1/file1.m'} {'/users/mss.system.v6zxt/Folder2/file1.m'}
ans = 2x1 cell array
{'/users/mss.system.v6zxt/file2.m' } {'/users/mss.system.v6zxt/Folder2/file2.m'}
