matlab function to return array until 0

i'm trying to create a function that receives an array and returns the array until a 0, for instance [12, -4, 5, 32, 0, 4, 1, -8] return [12, -4, 5, 32], and if the array contains no 0, return the whole array.

here's what i have so far:

function V = Notzero(V)
V(V==0)=[]
end

I an extremely new to Matlab though i know a bit of js, i believe what i wrote returns the array without the 0s, but im not sure. Any help appreciated

Try this:

function V = Notzero(V)
  zeroIndex = find(V == 0);
  if ~isempty(zeroIndex)
  V = V(1:zeroIndex-1)
  end
end

If it finds a zero, it redefines V. If it doesn't find a zero, zeroIndex is empty and it doesn't go into the "if" block and so V is returned completely unchanged.
