Hi, I need to generate a 1000 text (or dat) files to be fed into another software. I have two text files (aa.txt and bb.txt) and an equation that generates random numbers. The produced text (or dat) file is to be comprised of aa.txt , the randomly generated numbers and finally the contents of bb.txt.

You should to read help for sprintf and fprintf for operating with this code.

Also I used dirty solution for new string line for Windows: char([13,10]) because matlabs '\n' is not working on my computer. You may use '\n'.

Files={'aa.txt','bb.txt'};
Fids=[fopen(Files{1},'r'),fopen(Files{2},'r')];
DataBefore=textscan(Fids(1),'%s');
DataAfter=textscan(Fids(2),'%s');
fclose(Fids(1));
fclose(Fids(2));
for i=1:10
    %There you can name output files
    FID=fopen(sprintf('output_%i.txt',i),'w');
    for j=1:length(DataBefore{1})
        fprintf(FID,['%s',char([13,10])],DataBefore{1}{j});
    end
      RandomNumbers=rand(1e3,1);
      for j=1:length(RandomNumbers)
          %There you should define number printing type and length
          fprintf(FID,['%5.2f',char([13,10])],RandomNumbers(j));
      end
      for j=1:length(DataAfter{1})
          fprintf(FID,['%s',char([13,10])],DataAfter{1}{j});
      end
      fclose(FID);
  end

I made a mistake. Sorry. Below is better version.

DataBefore=fileread('aa.txt');
DataAfter=fileread('bb.txt');
for i=1:10
    %There you can name output files
    FID=fopen(sprintf('output_%i.txt',i),'w');
    fprintf(FID,'%s',DataBefore);
      RandomNumbers=rand(1e3,1);
      for j=1:length(RandomNumbers)
          %There you should define number printing type and length
          fprintf(FID,['%5.2f',char([13,10])],RandomNumbers(j));
      end
      fprintf(FID,'%s',DataAfter);
      fclose(FID);
  end
