Dear all, I'm trying to implement a logging facility. For that reason, I want to replace my current calls fprintf(log_fid,"some label: %d\n, some_var) for something like myfprintf("some label: %d\n, some_var) and then call fprintf from within myprintf. My problem is that I don't know how to specificy the variable arguments list, I've tried like this:
function myfprintf(varargin)
fprintf(log_fid,varargin)
end
but that obviously won't work. Any suggestions? Thanks in advance. Best regards, Juan

Hey, if you're doing logging in Matlab, consider trying my SLF4M framework instead of rolling your own: https://github.com/apjanke/SLF4M

Thank you, a couple of hours after asking the question I realized myself that I forgot the {:}
It works nice.

Try this one...
disp(sprintf('%d %d',log_fid,varargin));
