Hi,

I am using the function fgetl embedded in a loop and I want to read a line from a text file each time the loop runs. This works fine for the first iteration however I get an index exceeds Matrix dimensions error when i = 2. Each iteration I want to read the following line in the text file. Here is the code I am using:

for i = 1:(length_file - 1)
      % Read the current line from the list file and extract the case numnber
      % information from it:
      line = fgetl(fid_case(i));

Any suggestions on how to sort this out??

Thanks,

Robbie

Hi,

I guess fid_case comes from opening the file, i.e. something like

fid_case = fopen('myfile.txt');

If yes, then fid_case is a number denoting the file, no indexing:

line = fgetl(fid_case);
