How to put print statements in MEX files generated with codegen?

2 views (last 30 days)
I have a matlab function that I'm compiling into a MEX with codegen. I want to have some print statements in there, mostly because the thing is slowing to a crawl and I want to see where time is being spent. I can't figure out how to get things to print out right away. As it is, if I just leave semicolons off, the values all print at once after execution is complete. How can I make something print out right away?
I found another similar question to this, but couldn't make sense of the answer.

Perhaps if you flush the stdout at regular intervals, you will see the displayed statements immediately. You could try using coder.ceval to call fflush(stdout); or use the MATLAB equivalent, which according to this discussion is drawnow('update').
