MATLAB: Fopen function word altering loop

fopenlooptextscan

I am very new to matlab and I was love some help.

I have a set of data which is in the form 'Data_JAN.dat' and it goes from Jan-Dec and I want to create a loop which I can text scan them all and create a graph from each set of data. However I am haveing issues with the fopen in the loop and I was wondering if it is possible to create a loop which alters the name of the file being open.

This is the code i have for opening and reading one file:

fileID = fopen('Data_JAN.dat');
C = textscan(fileID,'%{dd MMM yyyy}D %{HH:mm:ss}D %4.2f');
fclose(fileID);
celldisp(C)

You are closing the file in the loop. close the file after the loop. I assume the below should work.

function read_datapattern(filename)
fid = fopen(filename,'rt');
if fid < 0
  error('error opening file %s\n\n',filename);
end
pattern = fgets(fid);
for n = 1:32767
  nextline = fgets(fid);
  pattern = strcat(pattern, nextline);
fprintf(pattern);
fprintf('\n');
end
fclose(fid);
