Hi
I have multiple text files (for example I have attaced here 2 files). I want to read them, and save the data into matrix. But I only want the data above the first dotted line (text left side to : in first column, and other data after : to the second column). Secondly, I want to save the data which is between two dotted lines (----). Again, the data under Item is in first column, and corresponding 3rd column in second column. Please help me some how to do this.

if your file always has the same amount of lines you could do something like this (if not, you need to check where the ---- occurs)
for ii = 1:Nfiles
fid = fopen(fileNames{ii});
if fid == -1
error('Unable to open txtfile');
end
fileData1{ii} = textscan(fid,'%s %s','Delimiter',':','HeaderLines',1,21);
fileData2{ii} = textscan(fid,'%s %s %s','Delimter','\t','HeaderLines',2);
fclose(fid);
end

of course this is something that you have to provide, I do not know how many files you have, nor where they are located. You can look into the dir() function to give you a list of fileNames and use numel(fileNames) to obtain Nfiles (=number of files)
p.s. it is madam
Hello Madam,
My files D:\Mekala_Backupdata\Matlab2010\Filesfolder\Try2. But the the number of text files will vary. I use the following code
clc
clear all
close all
FileList=dir('D:\Mekala_Backupdata\Matlab2010\Filesfolder\Try2/');
j=1;
for i=3:1:(size(FileList)) %%read all files from folder of specified dir
FileName{j}=FileList(i).name;
j=j+1;
end
for ii = 1:j
fid = fopen(fileNames{ii});
if fid == -1
error('Unable to open txtfile');
end
fileData1{ii} = textscan(fid,'%s %s','Delimiter',':','HeaderLines',1,21);
fileData2{ii} = textscan(fid,'%s %s %s','Delimter','\t','HeaderLines',2);
fclose(fid);
end
But it giving me below error:
??? Undefined variable "fileNames" or class "fileNames".
Error in ==> ReadTextFiles_0108_m1 at 12 fid = fopen(fileNames{ii});
Kindly help Madam

Change
FileName{j}=FileList(i).name;
to
FileNames{j}=FileList(i).name;
