MATLAB: Fzero function, not enough input arguments

error messagefunctionfzeronot enough input arguments

Hi!
I'm trying to calculate a simple function, separated in three parts (see code below). The function should be the input for a fzero function, where an extreme value for alpha is determined.
function time = uebung42(alpha)
x = 200;
y = 120;
yL = 70;
yW = y - yL;
vw = (7 * 1000) / 60 / 60;
vl = 3*vw;
term1 = (-yL * cos(alpha)) / (vl * (sin(alpha))^2);
term2 = yL * ((-sin(alpha))^2 - (cos(alpha))^2) * (x - (yL * cos(alpha)) / sin(alpha));
term3 = vw * (sin(alpha))^2 * sqrt( yW^2 + (x - (yL * cos(alpha)) / sin(alpha))^2);
time = term1 - ( term2 / term3);
end
Each individual term1-3 has a result and works fine, but when it try the fzero function, it gives me the following error message:
>> fun =  @uebung42
fun = 
      @uebung42
>> alpha = fzero(uebung42,1)
Error using uebung42 (line 11)
Not enough input arguments.
Line 11 means the calculation for term1, but I just can't seem to find whats wrong with it. Any ideas?

Best Answer

alpha = fzero(fun,1)
