Add LOTS of variables into my loop

Asked by C G
on 5 Apr 2018
Right now I have the code below. Ultimately I am trying to automate a program using Matlab. I have the batch file needed to run the program. I just need to figure out how to write a CONTROL file that the program needs. The loop below creates 4 control files, but overwrites each one with each iteration. Eventually, the program will run in the loop using the control file before it overwrites it.
The variables I need to change are listed as A-D. These come from the excel file, shown here. The line I am changing is the first line of the CONTROL file and it is just setting the date and hour for the program to start at. The CONTROL file needs to have a bunch of information and this is listed as variable P. The file names listed in P will eventually need to change, but I can work on that later.
What I need to do is expand the loop to include a lot more variables... well over 48000 if I analyze the complete set. But for now, let's go with just one month's worth of data, 125 variables. How do I add these to the loop?
Also if anyone knows how to read in data from ColumnF so that it looks like ColumnF data, i.e. 00 or 06 and not 0 or 6 or even worse "00" or "06", please share. The program needs to have the data as two digits. It doesn't like just one.
filename = 'Book1.xls';
sheet = 1;
xlRange1 = 'c2:f2';
xlRange2 = 'c3:f3';
xlRange3 = 'c4:f4';
xlRange4 = 'c5:f5';
A = xlsread(filename,sheet,xlRange1);
B = xlsread(filename,sheet,xlRange2);
C = xlsread(filename,sheet,xlRange3);
D = xlsread(filename,sheet,xlRange4);
F = {A,B,C,D};
for k = 1:numel(F)
[fid,msg] = fopen(sprintf('CONTROL',k),'wt');
assert(fid>=3,msg)
fprintf(fid,'%2.0f %2.0f %2.0f %2.0f %2.0f %2.0f',F{k}(1:4));
P={'';'3';'-71.166889 111.366531 10.0';'-71.166889 111.366531 2500.0';'-71.166889 111.366531
5000.0';'-240';'0';'30000.0';'5';'C:/hysplit4/MetData/gdas1.dec10.w5';
'C:/hysplit4/MetData/gdas1.dec10.w1';'C:/hysplit4/MetData/gdas1.dec10.w2';'C:/hysplit4/MetData/gdas1.dec10.w3';'C:/hy split4/MetData/gdas1.dec10.w4';
'./tdump10123018';} ;
% fid = fopen('data.txt','wt') ;
fprintf(fid,'%s\n',P{:});
% % % fclose(fid) ;
fclose(fid);
movefile('CONTROL', 'C:\hysplit4\working');
end
