I need to create a run file, I have several lines of code that I need a run file execute over a number of (.dat) files.
a simple, one run looks like this
option solver cplex;
model ABC.mod;
data a_1.dat;
What I need is to repeat that same commands with only 1 modification. each new time using a new (.dat) file.. I have the dat files numbered (i.e. a_1.dat, a_2.dat ,...., a_1000.dat)
I wrote the following code, however, I keep getting 1 file with 1 set of commands.
clear all;
TNOR=6; % total number of runs (i.e. total number of files the run file will go over one by one
for i = 1:TNOR
L1 = 'reset;';
L2 = 'option solver cplex';
L3 = 'model ABC.mod;';
s1 = 'data a_' ;
s2 = (num2str('%d', i)) ;
s3 = '.dat ;';
L5= 'solve;';
FID=fopen('','w'); % file identifier
fprintf(FID,'%s \n',L1, L2, L3); % print data of first file
fprintf(FID,'%s \n',L4);
fprintf(FID,'%s \n',L5);
fclose all;

solved it ;)
I was writing to the file not appending the new text..
Also I had a wrong way to add the number of the .dat file
the following are the two lines that I had a problem with
s2 = (num2str(i)) ;
FID=fopen('','a'); % file identifier

A better solution is to fopen your file before your loop, so it is wiped before your first iteration. You should also use the sprintf command for visual clarity or use the fprintf directly. It is also better to make a habbit of moving static assignments out of the loop.
Also, using i or j as loop iterator is generally not a good idea due to the possible confusion with the imaginary unit, in which case you should use 1i or 1j.
clear variables;
TNOR=6; % total number of runs (i.e. total number of files the run file will go over one by one
FID=fopen('','w'); % file identifier
L{1{} = 'reset;';
L{2} = 'option solver cplex';
L{3} = 'model ABC.mod;';
L{5}= 'solve;';
for ii = 1:TNOR
L{4}=sprintf('data a_%d.dat \n',ii);
fprintf(FID,'%s \n',L{:});% print data
fclose all;
