I am trying to make it so that when a file is uploaded the "name2" of my code will change to match the source file that the data was taken from. Code below.The pieces of code that i want to match are bold and italic.
fid = uigetfile('.dat');
[pathstr, name2 ,ext] = fileparts(fid);
S = importfile(fid); name = S.textdata;
x = S.data(:,1); y = S.data(:,2);
n = length(x);
a = ones(n,1); b = (1:n)'; z = zeros(n,1);
m = [a b x y z ; 1 0 0 0 0];
dlmwrite('coords_ name2 .txt',m,' ')

See this snippet:
% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = 'C:\Program Files\MATLAB';
if ~exist(startingFolder, 'dir')
% If that folder doesn't exist, just start in the current folder.
startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
fullFileName = fullfile(folder, baseFileName)
% Now read it in.
% Now create output name
baseOutputFileName = sprintf('Coords_%s', baseFileName);
fullOutputFileName = fullfile(folder, baseOutputFileName);

Thanks, here is what i did to make the file change.
clc clear all close all
fid = uigetfile('.dat');
[pathstr,name2,ext] = fileparts(fid);
S = importfile(fid); name = S.textdata;
x = S.data(:,1); y = S.data(:,2);
n = length(x);
a = ones(n,1); b = (1:n)'; z = zeros(n,1);
m = [a b x y z ; 1 0 0 0 0];
filename = sprintf('coords_%s.txt',name2);
dlmwrite(filename,m,' ')

Any reason why you threw out all the things in there that I used to make it more robust? I mean, why write fragile code when you don't have to?
