writing a matrix into a file
显示 更早的评论
Hello;
I have a matrix A, let's say it is a 100x1 matrix. I want to put the data into a text file, such that each line corresponds to the row of my matrix. How can I do it?

That depends on how you open your txt file, with wordpad you will get one column, with notepad you will get one line

Use
dlmwrite('file.txt',A,'newline','pc')

Just take transpose of your matrix and then write it to a file

There are many possible ways. One is to use the frprintf() function. See
doc fprintf
for syntax and examples.

Here's a basic script that you should be able to modify and get to work using fprintf. Look at the help document for other things you can specify, like field width.
homedir = cd; % Save current directory as home directory
nrows = size(A,1);
flnm = 'Matrix A'; % Specify string for filename
cd(newdir); % Change directory to new directory, if desired. Must specify string for new directory.
fid = fopen(flnm,'wt+'); % Create writable textfile
% Enter data into text file
for i = 1:nrows
fprintf(fid,'%f\r\n',A(i,:)); % The %f is for floating point numbers, or you could use %d for double-precision integers
end
% Close text file and return to home directory
fclose(fid);
cd(homedir); % Return to home directory
