Hello, I want to save a file with the format .txt in my desktop, not in matlab/Work. This is my program:
clear all;
Name_file=input('Tell me the name of the file(example.dat): ','s');
X=[ 0 0.5 0.75 1];
Y=[ 0 1 2 3];
A=[X' Y'];
[n,m]=size(A);
fid=fopen(Name_file,'w');
for i=1:n
for j=1:m
fprintf(fid,'%8.4f\t',A(i,j));
end
fprintf(fid,'\n');
end
fclose(fid);

Thank you Fangjun Jiang, my program will be: clear all; Name_file=input('Tell me the name of the file(example.dat): ','s'); X=[ 0 0.5 0.75 1]; Y=[ 0 1 2 3]; A=[X' Y']; [n,m]=size(A); fid=fopen(Name_file,'w'); for i=1:n for j=1:m fprintf(fid,'%8.4f\t',A(i,j)); end fprintf(fid,'\n'); end fclose(fid); [File,Folder]=uiputfile; dlmwrite(fullfile(Folder,File),A,'delimiter',' ','newline','pc');
I have a new problem, the file is save in desktop and at the same time in matlab/work and I don´t want it. How can I do for not saving in matlab/work?
Thank you

All you need is the lines that assign value to A and the last two lines to select a file and then write to the file. You don't need the for-loop anymore. That's probably why two files are created.
