merging two text files and generate 1000 copies of the new text (or dat) file

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

Dear Sergey Thanks for the answer that you've provided. however, the result does not appear identical to the way it is presented in the files aa.txt and bb.txt.

Please allow me to illustrate: lets say that aa.txt contents are:

first file ,,, first line

First file ,,, second line

1234.1234

the output of the above code is

first

file

,,,

first

line

First

file

,,,

second

line

1234.1234

it appears as if it is inserting a new line after each space, I think if that can be mitigated then all is well.

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

Yes, dear Sergey, it is fully working now

Thank you very much indeed
