I can open my data file with this code:
fp= fopen('ecg.txt','rt');
fgets(fp);
A = textscan(fp, '%f');
fclose(fp);
result=A{:};
%....Function....
But it can only open the ecg.txt file. how can i open another data file by browsing it? I tried this one:
[filename1,filepath1]=uigetfile({'*.txt*','Text Files'},...
'Select Data File 1');
cd(filepath1);
opener1=load([filepath1 filename1]);
fp= fopen('filename1','rt');
fgets(fp);
A = textscan(fp, '%f');
result=A{:};
%....Function....
But getting errors and can't fix. Can anyone help? Thanks in advance!

If you use:
cd(filepath1);
You shouldn't need to use "filepath1" again.
opener1=load([filename1]); %reads matlab files - if you open it with "fopen", you don't need to use this line.
Remember to close the file once you've read it.
AND, importantly, since you change directory, your code might be no longer accessable. You need to ensure that your code is on the matlab path.
