I have 20 csv files named differet names, I want to make a program to rename them so they will be numbered this way :
  • M_1_1
  • M_1_2
  • M_1_3
  • And so on ...
When I use this code :
filename_M_1 = strcat('M_1_%g.xlsx'); % g is the number of files in the directory, I put on the top of the program for g=3:length(Folders) to run the list of files in the directory
xlswrite(filename_M_1,D,1,'A1') %D is the matrix
I have a result like this :
Any ideas ? thanks for help

Silver - try using sprintf to create your file name
for k = 1:20
filename = sprintf('M_1_%d.xlsx', k);
% create new file
% your code here
end
