MATLAB: How to go through each element of a vector without a for loop

for loopMATLAB

I would like to write the following code without a for loop. Thanks in advance! 
function fh = poly_fun(p)
  function polynomial = poly(x)
    polynomial = 0; 
    for ii = 1:length(p)
      polynomial = polynomial + p(ii) .* x.^(ii-1);
    end
  end
  fh = @poly;
end

Best Answer

If P is an array of coefficients and x is the value
n = length(p)-1 ; 
iwant = sum(p.*x.^(n:-1:0))
If x is an column array
iwant = sum(sum(p.*x.^(2:-1:0),2)) ;
