This is your 107th question in this forum. It is time to learn how to include all necessary details to a question. Currently you could get an acceptence rate of only 19%. Improving the quality of your questions would be a very good idea.

E.g. at first you are talking of the vector A and explain, what the values mean. But for the actual problem rand(1,4) would be equivalent also. In opposite to such unnecessary information, it is not explained anywhere whar "A1" and "A100" is. Later on in this thread it comes out, that you can to save a struct instead.

Finally, when I see the bunch of problems you have posted here, it is very hard for me to imagine, that you cannot find out, how to write some numbers to a file. Pat, this is extremly basic.

Hello, Pat

I just give you small example.

Then, I hope you can use it or do modification on it for your purpose.

clear; clc;
for cnt = 1 : 10
    m = 255*rand;
    V = 255*rand;
    SD = 255*rand;
      filename = strcat(pwd,'\New1\A',num2str(cnt),'.txt');
      fid = fopen(filename, 'w');
      fprintf(fid,'mean : %.2f\n variance : %.2f\n standard dev : %.2f\n',m,V,SD);
      fclose(fid);
  end

@Chandra: FULLFILE is more secure than "strcat(pwd,'\New1\A',num2str(cnt),'.txt')". e.g. if the current folder is "C:\" the trailing file separator is considered.

@Pat: You've asked a question and Chandra gave a working asnwer. Afterwards you modify the conditions. It is obvious that this wastes the time of Chandra and all others who want to assist here.
