It would be simpler if you had named the files so they would sort lexically as C001, C002, ... etc., but it's still not too bad...
N=864; % the number files -- better/more general would be to use dir() and count number returned
L=60000; % length of each -- better/more general would be to read first and determine its length
M(L,N)0; % preallocate the output array to those sizes
for i=1:N
fname=char("C"+i+.txt);
M(:,i)=readmatrix(fname);
end
If the filenames were in proper normalized format, I'd be inclined to use the OS to copy and concatenate all into one long file, then read and reshape the resulting long vector instead of the loop...

You can type as easily as I ... you've got to put at least SOME effort into solving your own problems rather than relying on being spoon-fed.
