What condition to use for checking whether at least a single negative element in a array?

24 views (last 30 days)
For example, what condition to use instead of '<' to execute the content inside if (to check if whether at least a single negative entry exists)?
A=[1;-1];
B=[3;4];
if (A.*B < 0)
disp (A.*B)
end

Use the 'any' logical function.
if any(A.*B<0)
If you are dealing with an array, C, of more than one dimension, do this:
if any(C(:)<0)
