I am trying to compare two filenames. I've assigned the filenames to varialbles, and I'm trying to compare the file names, if they match i need to perform some functions, if they do not match i need to skip.
Here's my code. It's inefficient, but It does what I need right now and I don't have time to go back and make it better.
clc;
clear all;
file = uigetdir;
contents = dir(file);
Data = fullfile(file,'Data')
for i = 1:length(contents)
[null,fName,fExt] = fileparts(contents(i).name);
L = strlength(fName);
G = L>10;
if G == 1
switch lower(fExt)
case '.txt'
samplefile = readcell(fName);
disp('1')
file2 = fullfile(Data,'*.txt');
specontents = dir(file2);
SampleID = cell2mat(samplefile(7,1))
for k = 1:length(specontents)
[null, fName1, fExt1] = fileparts(specontents(k).name);
specimenfile = readcell(fName1);
SpecID = cell2mat(specimenfile(3,2))
if SampleID == SpecID
disp('yes')
else
continue
end
% if sample ID in sample file == sample ID in specimen file
%disp(test)
end
%if samplefile <= length(samplefile)
%samplefile = readcell(fName)
%SampleID = cell2mat(samplefile(7,1))
% disp(speciminfile)
disp('YAY')
continue
end
else
disp('toss')
end
%disp('end')
end
disp('end')

So is your question how to shorten your code? Maybe try this statement
if strcmp(filename1, filename2)
% Whatever you want it to perform if they are identical
end
Otherwise, if you do not look for completely identical filenames, there is the function contains().
