MATLAB: How to open a file if the user enters multiple parts of file name

Question

I currently have the following code with the help of Stephen Cobeldick:

function myopen( str )
cd '[location to folder where search is taking place]';
S = dir(sprintf('*%s*.txt',str));
cellfun(@winopen,{S.name});
cd '[location to current folder where matlab file is located]'
end

This code will open a file when part of the file name is entered. For example: If the user enters cat and the files available are 1) cat_dog_bird.txt 2) cheetah_lion_tiger.txt and 3) shark_whale_dolphin.txt the code should open the cat_dog_bird.txt file in a notepad editor (a windows software).

If the user enters dog then the code should still open the cat_dog_bird.txt file in a notepad editor.

Now what I am trying to do is to find a way when the user enters two or more words the code should open the file which has both the words. I tried to manipulate the code a bit but was not able to.

For Example: The files present are cats_dogs_lions.txt , cats_cheetah_goat.txt and cats_hyenah_dog. I want to write a code which will allow the user to open a file which will open the file cats_dogs_lions.txt if the user enters cats & lions and will open the file cats_cheetah_goat.txt if the user enters cats & cheetah.

Thanks in advance!

Try this:

function myopen(varargin)
D = 'test'; % the directory
S = dir(fullfile(D,'*.txt'));
N = {S(~[S.isdir]).name};
F = @(p)cellfun('isempty',strfind(N,p));
X = cellfun(F,varargin,'uni',0);
C = N(all(~vertcat(X{:}),1));
cellfun(@(f)winopen(fullfile(D,f)),C);
end

Used like this:

myopen('cat','dog')
