I have a series of plain text files that I need to import into matlab. Matlab imports these files as numerical arrays, and I only want the 3rd and 5th columns of each file. I have a for loop that imports each file into matlab and makes it a numerical array, but I want to take that further and remove the columns I don't want, and then save the new files back to the directory. Here's the code I have so far:
>> files = dir('*.pck'); %this creates a string of all the files of a specific extension% in a directory. This part works fine.>> for i=1:21 %just the number of files I have in this specific case. This also works fine.eval(['load ' files(i).name]); %I was only able to do this after 3 hours of googling.% It loads the files, makes each one a variable with the file's name as the variable name,% it works perfectly.
If I end the loop there then all the files I need are loaded and I can filter each one and save each one by hand, but it feels like I should be able to do this with a loop, I just don't know how to do it. The only thing I can think to try is:
files(i).name = files(i).name(:,[3,5]);
in the same loop hoping it would do make new variables with only the 3rd and 5th columns, but that doesn't work.
Any help at all would be greatly appreciated.
