Yes! I agree with this change. But constructions with condition in the left
part such as
y(x>10)=y(x>10)+1;
at false condition cause the same result in 5.5.2 and 6.0.0. Therefore, the
warning is not required in this special case. Now I will use additional "if"
block to bypass this warning:
if or(x>10) then
y(x>10)=y(x>10)+1;
end
B.r.

I have problems with new warning "Warning adding a matrix with the empty matrix
will give an empty matrix result.".
A construction such as
y(x>10)=y(x>10)+1;
produce the warning in 6.0.0 version if all of x<10. It is very critical if
such construction is in a cost function of optimization, function for zero
search or other iteration process.
If millions of calculations of the affected function is required, the time
consumption significantly increases and the output will be littered and
unreadable. Using warning('off') usually is not good idea because it can
suppress some important warning during the calculation. Is it possible to
suppress the warning separately?
Multiplication, division or power do not produce the same warning.
With best regards.
Viktor.
