Hi,
Use fopen and fclose to handle these files.
use fopen to get the file id (pay that in case of failure fileID will be -1 )
shortly:
Premission 'r' to read and 'w' to write.
fileID = fopen(fullfilename,'r')
if(fileID!=-1)
% do something. use fgetl
end
Then I usually use fgetl to process every line and status feof to know if the file ended but there are more ways of course.
while ~feof(fileID)
tline(k) = fgetl(fileID)
end
dont forget to close the file afterwards
fclose(fileID)
After that when you want to write to a file open it with the 'w' permission and use fprintf to write to a file
fprintf(fileID,formatSpec,A1,...,An)
Again, remember to close the file when you're done with fclose
Hope this helps
