File in use error, fclose not enough?

Hello,

I have the following problem. My plan was to write a txt file in matlab. This file contains the data to open in another program for controlling a robot.

    fid = fopen('filename','wt');
    for (i=1:amount)
            fprintf(fid, '%s\n',my_cell{i});
    end 
    fclose(fid)

When I run the file I want to be able to open the file in that other program. But it says 'file in use'. Is there a way to avoid this? Apparently fclose(fid) is not enough..

Thanks!

Is it possible that you had fopen()'d it without fclose() in a run that error'd? If so then it would still be open. Have you tried exiting MATLAB and then trying?

If this wouldn’t interfere with other file operations you’re doing:

fclose('all')

might work.

Oh! thanks a lot! It seems like that was the problem, should've tried that myself!
