cd('D:\coding\datawave');
fid=fopen('file_21.txt');
data=textscan(fid,'%s %s %s %f %f');
height=cell2mat(data(4));

Do as sugested by previous answer, import, fscanf, textread, load... if it doesn't have any structer. If it does i suggest to use excel and xlsread. It can save you a lot of time.

dear sir, thanks for your respond. what I try is to call the text file window to be display without no need to manually change text file name. I meant current directory of my file will display, then just clicking which one to be exist one my current folder.
