Dear everyone,
Please help me to solve this problem. I need to make a code that can read data from a text file. The format of the file is as follows:
0.1 ABC63-820
0.5 ABC63-818
1.0 ABC63-813
I want to take out two variables like this:
X=[0.1 0.5 1.0];
Y=[20 18 13]
Can anyone help me to write a code to take out these data?
Thank you so much!

Dear Phan,
textscan can do the job:
>> fid=fopen(filename);
>> data=textscan(fid,'%f ABC63-8%d');
>> fclose(fid);
>> x=data{1};y=data{2};
Best regards,
Michael

It would have been easier if you'd said that right from the beginning.
So now, we first read the second part as string and then split it. There might be different ways to split, but this one will work:
fid=fopen('test1.txt');
data=textscan(fid,'%f %s');
fclose(fid);
x=data{1};
[Z,y]=cellfun(@(x) deal(x(1:end-2),str2num(x(end-1:end))),data{2},'uniform',false);
Y=cell2mat(y);
