Re: function printing progress to terminal while running

[Tatsuro MATSUOKA]

Hi

octave:16> help stderr 
-- Built-in Function: stderr () 
Return the numeric value corresponding to the standard error 
stream. Even if paging is turned on, the standard error is not 
sent to the pager. It is useful for error messages and prompts.

So try

fprintf(stderr(), "Iteration:%d",K)
