I'm not sure how this would be useful since a program shouldn't rely on what m-files are opened.

Nevertheless, define the file name of the opened file in the first line below. If the file is opened in the editor, it should close. Otherwise, nothing should happen.

filename = 'myfile.m';
openedfiles = matlab.desktop.editor.getAll;
allfnames = cellstr({openedfiles.Filename});  % see note below
idx = endsWith(allfnames, filename);
close(openedfiles(idx))

Note: with Matlab Online (R2021a, Linux) openedfiles.Filename returns strings but on my local system (R2021a, Windows) openedfiles.Filename returns a cell array of character vectors. cellstr() is used to satisfy both systems.

my file (myfile.m) still isn't closing when i press my designated button. any ideas?

I just changed the 3rd line by replacing square brackets with curly brackets. That should fix it.

@Joseph Kutteh

I'm going to change the answer one more time so that it works across multiple platforms. Oddly, with Matlab Online (R2021a, running Linux) openedfiles.Filename returns strings which is why the square brackets worked. But when I run this on my home installation (R2021a, Windows), openedfiles.Filename returns character vectors within a cell array. To satisfy both systems, I'm adding cellstr() which will convert the string arrays and will leave the cell arrays unchanged.
