Multidimensional Array indexing to a single vector

I want to check to see if a portion of each column of my array meets a criteria and if it does give a value of 1 and if it doesn't, 0. So x=B(1:5,:)>10 and if B is a 10X10 array, I would like to have x be a 1X10 column vector of ones or zeros. I know this can be done with a loop, but is there anyway to do it without one?

You do not indicate how you want to transform the 5 x 10 result of B(1:5,:)>10 into a 1 x 10 vector (incidentally, 1 x 10 is a row vector). Perhaps you want

any(B(1:5,:)>10)

or

all(B(1:5,:)>10)

Thanks for those commands and yes you're right I meant a row vector.

sum(B(1:5,:)>10)>0

This would be equivalent to the any() code.
