hi, this is a simple question

v='C:\Users\punith\Desktop\1.txt';% path

how to read text file using v

Best Answer

Use fopen to open the file and then use fscanf or fgetl to read in the content. You can also use fread. For example, the following code reads the first line of the text.

fid = fopen(v,'r');
tline = fgetl(fid);
fclose(fid)

Just to remember close the file using fclose afterwards.

doc fopen
doc fclose
doc fread
doc fscanf
doc fgetl

Hi!

count = 1;
tline = fgetl(fid01);
while ischar(tline)
count = count + 1;
disp(tline)
if count == 3
fprintf(fid02,'%s\r\n',tline);
end
tline = fgetl(fid01);
end 
fclose(fid01);
fclose(fid02);

You can do as well

for n = 1:3
tline = fgetl(fid01);
end
fprintf(fid02,'%s\r\n',tline);
fclose(fid01);
fclose(fid02);

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);
