Loading text files using variable names
显示 更早的评论
Hi, Is there any way of loading a text file (say mydata.txt) using a variable name? What I need to do is allow the user to input the name of a text file, which contains an array, in the previous command, and then for the program to load the file with name and store it into another variable. Thanks in advance.

filename = input('Enter the file name (without the txt extension)','s');
fid = fopen([filename '.txt']);
C = textscan(fid, <format to be used>);
fclose(fid);

It depends on what data type it is and how the data is delimited. Assuming a simple text file with:
5.2 5.3 5.4
6.5 6.6 6.7
7.8 7.9 8.0
You'll need something like:
C = textscan(fid,'%f %f %f','CollectOutput',1);
HTH,
