Re: warning: implicit conversion from numeric to char

[mmuetzel]

The warning comes from lines similar to this:
num2str([Decision, sprintf('0.5 ') , sprintf('-1')])

I didn't dive deep enough into your code to guess what you are actually
trying to do. But the result of sprintf is a char vector (fwiw the argument
already is). Your variable Decision is an empty numeric array which is
converted into a char array to do the concatenation with the chars. Hence
the warning.
num2str on a char vector returns the same char vector...
