@matt,

Yes, I knew MATLAB was doing something like that. It was not the point of the video, so I just ignored it. Glad to see someone noticed that in there!

Petr,

It is funny, I give a “Doug’s impossible MATLAB quiz” to many of the new hires in technical support. Someone started doing the sprintf thing, and I guessed that she was a C programmer. She was all like “How did you know that?”

Funny how that works. I have never internalized the use of sprintf, even after 15 years of programming MATLAB!

I do not know why (maybe because I have background in those old fashioned languages like C), for a long time I prefered to write

title( sprintf( ‘%s: %d’, str, num ) );

I have learned about this [’a’ ‘b’] way of doing it rather recently, but I have not get used to that yet. Although a bit more cryptic, sprintf gives me more freedom in formating the result.

For any who might be interested in why you got an asterisk.

char(42)
double(’*')

Matlab did a little num2str on it’s own, though not in the way which was desired!
