suppose i have a vector 'bw' if in there value '0' exist than total value of bw=0 is estimated.

bw=[120 1322 5542 5653 0 0 0 45451]; than bw=0 because zero exist in vector....if bw=[121 5454 24 54 4 5454 545 4654]; than bw=121;

bw=[120 1322 5542 5653 0 0 0 45451]

if any(bw==0)
    bw = 0

else
    bw=bw(1)
end

the above code demonstrates, if any value is zero in bw it displays zero, if not displays first element of bw
