When I run the following code it only shows the last file in the directory in MATLAB workspace? How do I get all the files in my directory saved in the workspace?

ivsFiles = dir('*.ivs');
numfiles = length(ivsFiles);
for k = 1:103;
filename = ivsFiles(k).name;
fileID = filename;
C = textscan(filename,'%d');
end

But I have files ra1001 to ra1150. How do I open and read all the files in the directory? Thanks for your help.

I tried this code:

ivsFiles = dir('*.ivs');
numfiles = length(ivsFiles);
for k = 1:103;
filename = ivsFiles(k).name;
fileID = filename;
fid = fopen('ra%d.ivs',k);
C = textscan(fid,'%d');
fclose(fid);
end
It is giving error:

Error using fopen Invalid permission.

My files do not have any password settings on them.

ivsFiles = dir('*.ivs');
numfiles = length(ivsFiles);
C = cell(numfiles,1) ;  % initialize each file's data into a cell 
for k = 1:numfiles;
filename = ivsFiles(k).name;
fileID = filename;
C{i} = textscan(filename,'%d');
end

Please note that, you will eat up the memory if the files are huge.
