Hi,
I want to copy some file but the path were they are going has a variable in its name
ex:
for compteur=1:1 nomaccel=fscanf(fidacc2,'%s',1); % read the name of the folder in a file
copyfile('LireDonneesDH.m','..\nomaccel\','f') %nomaccel is the variable copyfile('CompterLigne.m','..\nomaccel\','f') copyfile('GraphiqueDH.m','..\nomaccel\','f') cd (nomaccel); run GraphiqueDH cd .. end
So Matlab needs to understand that nomaccel is a variable.
I'm not sure how to do this
Thx for helping me !

Hello french fellow, you may be old now but for people coming on this page i would like to try an answer :
I would define first the path with dynamic strings :
destination_file_name = fscanf(fidacc2,'%s',1); % read the name of the folder in a file
destination_file_path = ([ '..\' , destination_file_name , '\' ]) %which gives > destination_file_path = '..\destination_file_name\'
%if you want to use numbers in the file name, you can also use 'num2str' function in the destination_file_path variable
copyfile('LireDonneesDH.m',destination_file_path,'f')

We recommend using fullfile() instead of concating together directories as character vectors.
