Generic code for Reading from Files:

The generic code to complete this is as shown below:

fid = fopen('filename');

if fid == -1

disp('File open not successful')

else

while feof(fid) == 0

% Read one line into a string variable

aline = fgetl(fid);

% Use string functions to extract numbers, strings,

% etc. from the line

% Do something with the data!

end

closeresult = fclose(fid);

if closeresult == 0

disp('File close successful')

else

disp('File close not successful')

end

The permission string can be involved in the call to the fopen function, for illustration,

fid = fopen('filename', 'r');

but is not essential as reading is the default. The condition on the while loop can be interpreted by saying "while the file end-of-file is false." The other way to write this is

while feof(fid)

that is interpreted as "while we're not at the end of the file."
