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?

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
