Using a while loop with a vector

Hey guys I'm running in to a problem with a 'while loop'. A simplified version of my codes look likes this:

B = [361;362;363;1000;10000;100000];

while B > 360
    B = B - 360;
end

which yields:

B =
           1
           2
           3
         640
        9640
        99640

What I dont understand is this: why does my while loop not repeat until the last three elements of my matrix are < 360.

Thanks in advance

Your while loop actually only runs once because after the first iteration, B>360 returns a logical array of [0 0 0 1 1 1], so it does not loop a second time. I think you meant to do something like this:

B = [361;362;363;1000;10000;100000];

for i = 1:numel(B)
    while B(i) > 360 
        B(i) = B(i) - 360;
    end
end

which will return:

     1
     2
     3
   280
   280
   280
