write_ascii
Writes large matrices to an ascii file. Format is up to user. Function automatically appends to file. It is many times (10-20X) faster than dlmwrite and almost as fast as using a mex file. Uses sprintf and fwrite (opposed to fprintf).
Example usage:
M = rand(1e5,3)*1000;
tic;dlmwrite('test.txt',M,'delimiter','\t','precision','%9.3f');toc;
tic;write_ascii('test2.txt',M,'\t','%9.3f');toc;
Elapsed time is 7.446049 seconds.
