My code is to find the roots of a quadratic using a row vector as the input. The function is called using myquad([3 4 5]) and I keep getting the error that i dont have enough input arguments. I am VERY new to matlab so please explain your answer like you're talking to a bump on a log.

function x = myquad(a,b,c)
if b^2 - 4*a*c > 0
    x = 2;
else if b^2 - 4*a*c == 0
    x = 1;
else 
    x = 0;
end
end

在 MATLAB Online 中打开

function x = myquad(vec)
  a = vec(1);
  b = vec(2);
  c = vec(3);
  if b^2 - 4*a*c > 0
    x = 2;
  else if b^2 - 4*a*c == 0
    x = 1;
  else 
    x = 0;
  end
end
