You can generate the list of file names with dir:
filelist=dir(fullfile(folder,'*_*.tif'));
Now you can optionally loop through this struct and remove any files that don't match the pattern of files you would like to read. (if you loop backwards, you don't need to worry about skipping any of the elements)
for n=numel(filelist):-1:1
if SomeCondition
filelist(n)=[];
end
end
And now you can use the struct to feed the file names to the geotiffread function, just like the documentation describes:
A=cell(size(filelist));
R=cell(size(filelist));
for n=1:numel(filelist)
fn=fullfile(folder,filelist(n).name);
[A{n},R{n}] = geotiffread(filename);
end
